Struct rustc_middle::ty::TyCtxt
source · pub struct TyCtxt<'tcx> {
gcx: &'tcx GlobalCtxt<'tcx>,
}
Expand description
The central data structure of the compiler. It stores references to the various arenas and also houses the results of the various compiler queries that have been performed. See the rustc dev guide for more details.
An implementation detail: TyCtxt
is a wrapper type for GlobalCtxt,
which is the struct that actually holds all the data. TyCtxt
derefs to
GlobalCtxt
, and in practice TyCtxt
is passed around everywhere, and all
operations are done via TyCtxt
. A TyCtxt
is obtained for a GlobalCtxt
by calling enter
with a closure f
. That function creates both the
TyCtxt
, and an ImplicitCtxt
around it that is put into TLS. Within f
:
- The
ImplicitCtxt
is available implicitly via TLS. - The
TyCtxt
is available explicitly via thetcx
parameter, and also implicitly within theImplicitCtxt
. Explicit access is preferred when possible.

pub fn eval_default_body_stability( self, def_id: DefId, span: Span ) -> EvalResult
Evaluates the default-impl stability of an item.
Returns EvalResult::Allow
if the item’s default implementation is stable, or unstable but the corresponding
#![feature]
has been provided. Returns EvalResult::Deny
which describes the offending
unstable feature otherwise.

) -> bool
pub fn check_stability( self, def_id: DefId, id: Option<HirId>, span: Span, method_span: Option<Span> ) -> bool
Checks if an item is stable or error out.
If the item defined by def_id
is unstable and the corresponding #![feature]
does not
exist, emits an error.
This function will also check if the item is deprecated.
If so, and id
is not None
, a deprecated lint attached to id

pub fn check_stability_allow_unstable( self, def_id: DefId, id: Option<HirId>, span: Span, method_span: Option<Span>, allow_unstable: AllowUnstable ) -> bool
Checks if an item is stable or error out.
If the item defined by def_id
is unstable and the corresponding #![feature]
does not
exist, emits an error.
This function will also check if the item is deprecated.
If so, and id

) -> bool
pub fn check_optional_stability( self, def_id: DefId, id: Option<HirId>, span: Span, method_span: Option<Span>, allow_unstable: AllowUnstable, unmarked: impl FnOnce(Span, DefId) ) -> bool
Like check_stability
, except that we permit items to have custom behaviour for
missing stability attributes (not necessarily just emit a bug!
). This is necessary
for default generic parameters, which only have stability attributes if they were
added after the type on which they’re defined.
Returns true
if item is allowed aka, stable or unstable under an enabled feature.

sourcepub fn const_eval_poly(self, def_id: DefId) -> EvalToConstValueResult<'tcx>
pub fn const_eval_poly(self, def_id: DefId) -> EvalToConstValueResult<'tcx>
Evaluates a constant without providing any substitutions. This is useful to evaluate consts
that can’t take any generic arguments like statics, const items or enum discriminants. If a
generic parameter is used within the constant ErrorHandled::ToGeneric
will be returned.
sourcepub fn const_eval_resolve(

) -> EvalToConstValueResult<'tcx>
pub fn const_eval_resolve( self, param_env: ParamEnv<'tcx>, ct: UnevaluatedConst<'tcx>, span: Option<Span> ) -> EvalToConstValueResult<'tcx>
Resolves and evaluates a constant.
The constant can be located on a trait like <A as B>::C
, in which case the given
substitutions and environment are used to resolve the constant. Alternatively if the
constant has generic parameters in scope the substitutions are used to evaluate the value of
the constant. For example in fn foo<T>() { let _ = [0; bar::<T>()]; }
the repeat count
constant bar::<T>()
requires a substitution for T
, if the substitution for T
is still
too generic for the constant to be evaluated then Err(ErrorHandled::TooGeneric)
is
returned.

pub fn const_eval_global_id_for_typeck( self, param_env: ParamEnv<'tcx>, cid: GlobalId<'tcx>, span: Option<Span> ) -> EvalToValTreeResult<'tcx>

sourcepub fn reserve_alloc_id(self) -> AllocId
pub fn reserve_alloc_id(self) -> AllocId
Obtains a new allocation ID that can be referenced but does not yet have an allocation backing it.
Make sure to call set_alloc_id_memory
or set_alloc_id_same_memory
before returning such
an AllocId
from a query.
sourcefn reserve_and_set_dedup(self, alloc: GlobalAlloc<'tcx>) -> AllocId
fn reserve_and_set_dedup(self, alloc: GlobalAlloc<'tcx>) -> AllocId
Reserves a new ID if this allocation has not been dedup-reserved before. Should only be used for “symbolic” allocations (function pointers, vtables, statics), we don’t want to dedup IDs for “real” memory!
sourcepub fn reserve_and_set_static_alloc(self, static_id: DefId) -> AllocId
pub fn reserve_and_set_static_alloc(self, static_id: DefId) -> AllocId
Generates an AllocId
for a static or return a cached one in case this function has been
called on the same static before.
sourcepub fn reserve_and_set_fn_alloc(self, instance: Instance<'tcx>) -> AllocId
pub fn reserve_and_set_fn_alloc(self, instance: Instance<'tcx>) -> AllocId
Generates an AllocId
for a function. Depending on the function type,
this might get deduplicated or assigned a new ID each time.
sourcepub fn reserve_and_set_vtable_alloc(
self,
ty: Ty<'tcx>,
poly_trait_ref: Option<PolyExistentialTraitRef<'tcx>>
) -> AllocId
pub fn reserve_and_set_vtable_alloc( self, ty: Ty<'tcx>, poly_trait_ref: Option<PolyExistentialTraitRef<'tcx>> ) -> AllocId
Generates an AllocId
for a (symbolic, not-reified) vtable. Will get deduplicated.
sourcepub fn reserve_and_set_memory_alloc(self, mem: ConstAllocation<'tcx>) -> AllocId
pub fn reserve_and_set_memory_alloc(self, mem: ConstAllocation<'tcx>) -> AllocId
Interns the Allocation
and return a new AllocId
, even if there’s already an identical
Allocation
with a different AllocId
.
Statics with identical content will still point to the same Allocation
, i.e.,
their data will be deduplicated through Allocation
interning – but they
are different places in memory and as such need different IDs.
sourcepub fn try_get_global_alloc(self, id: AllocId) -> Option<GlobalAlloc<'tcx>>
pub fn try_get_global_alloc(self, id: AllocId) -> Option<GlobalAlloc<'tcx>>
Returns None
in case the AllocId
is dangling. An InterpretCx
can still have a
local Allocation
for that AllocId
, but having such an AllocId
in a constant is
illegal and will likely ICE.
This function exists to allow const eval to detect the difference between evaluation-
local dangling pointers and allocations in constants/statics.
sourcepub fn global_alloc(self, id: AllocId) -> GlobalAlloc<'tcx>
pub fn global_alloc(self, id: AllocId) -> GlobalAlloc<'tcx>
Panics in case the AllocId
is dangling. Since that is impossible for AllocId
s in
constants (as all constants must pass interning and validation that check for dangling
ids), this function is frequently used throughout rustc, but should not be used within
the interpreter.
sourcepub fn set_alloc_id_memory(self, id: AllocId, mem: ConstAllocation<'tcx>)
pub fn set_alloc_id_memory(self, id: AllocId, mem: ConstAllocation<'tcx>)
Freezes an AllocId
created with reserve
by pointing it at an Allocation
. Trying to
call this function twice, even with the same Allocation
will ICE the compiler.
sourcefn set_alloc_id_same_memory(self, id: AllocId, mem: ConstAllocation<'tcx>)
fn set_alloc_id_same_memory(self, id: AllocId, mem: ConstAllocation<'tcx>)
Freezes an AllocId
created with reserve
by pointing it at an Allocation
. May be called
twice for the same (AllocId, Allocation)
pair.

Replaces all regions bound by the given Binder
with the
results returned by the closure; the closure is expected to
return a free region (relative to this binder), and hence the
binder is removed in the return type. The closure is invoked
once for each unique BoundRegionKind
; multiple references to the
same BoundRegionKind
will reuse the previous result. A map is
returned at the end with each bound region and the free region
that replaced it.
Panics
This method only replaces late bound regions. Any types or
constants bound by value
will cause an ICE.

bound regions; the fld_t
closure replaces escaping bound types and the fld_c
closure replaces escaping bound consts.

Replaces all types or regions bound by the given Binder
. The fld_r
closure replaces bound regions, the fld_t
closure replaces bound
types, and fld_c
replaces bound constants.

.

Should only be called if ty
has no inference variables and does not
need its lifetimes preserved (e.g. as part of codegen); otherwise

sourcepub fn destructor_constraints(self, def: AdtDef<'tcx>) -> Vec<GenericArg<'tcx>>
pub fn destructor_constraints(self, def: AdtDef<'tcx>) -> Vec<GenericArg<'tcx>>
Returns the set of types that are required to be alive in
order to run the destructor of def
(see RFCs 769 and
1238).
Note that this returns only the constraints for the
destructor of def
itself. For the destructors of the

pub fn uses_unique_placeholders_ignoring_regions( self, args: GenericArgsRef<'tcx> ) -> Result<(), NotUniqueParam<'tcx>>
Checks whether each generic argument is simply a unique generic placeholder.
This is used in the new solver, which canonicalizes params to placeholders for better caching.
sourcepub fn is_closure(self, def_id: DefId) -> bool
pub fn is_closure(self, def_id: DefId) -> bool
Returns true
if def_id
refers to a closure (e.g., |x| x * 2
). Note
that closures have a DefId
, but the closure expression also
has a HirId
that is located within the context where the
closure appears (and, sadly, a corresponding NodeId
, since
those are not yet phased out). The parent of the closure’s
DefId
will also be the context where it appears.
sourcepub fn is_typeck_child(self, def_id: DefId) -> bool
pub fn is_typeck_child(self, def_id: DefId) -> bool
Returns true
if def_id
refers to a definition that does not have its own
type-checking context, i.e. closure, generator or inline const.
sourcepub fn is_trait(self, def_id: DefId) -> bool
pub fn is_trait(self, def_id: DefId) -> bool
Returns true
if def_id
refers to a trait (i.e., trait Foo { ... }
).
sourcepub fn is_trait_alias(self, def_id: DefId) -> bool
pub fn is_trait_alias(self, def_id: DefId) -> bool
Returns true

),
and false
otherwise.
sourcepub fn is_constructor(self, def_id: DefId) -> bool
pub fn is_constructor(self, def_id: DefId) -> bool
Returns true

, and false
otherwise.
sourcepub fn typeck_root_def_id(self, def_id: DefId) -> DefId
pub fn typeck_root_def_id(self, def_id: DefId) -> DefId
Given the DefId
, returns the DefId
of the innermost item that
has its own type-checking context or “inference environment”.
For example, a closure has its own DefId
, but it is type-checked
with the containing item. Similarly, an inline const block has its
own DefId
but it is type-checked together with the containing item.
Therefore, when we fetch the
typeck
the closure, for example, we really wind up
fetching the typeck
the enclosing fn item.
sourcepub fn closure_env_ty(
self,
closure_def_id: DefId,
closure_args: GenericArgsRef<'tcx>,
env_region: Region<'tcx>
) -> Option<Ty<'tcx>>
pub fn closure_env_ty( self, closure_def_id: DefId, closure_args: GenericArgsRef<'tcx>, env_region: Region<'tcx> ) -> Option<Ty<'tcx>>
Given the DefId
and args a closure, creates the type of
self
argument that the closure expects. For example, for a
Fn
closure, this would return a reference type &T
where
T = closure_ty
.
Returns None
if this closure’s kind has not yet been inferred.
This should only be possible during type checking.
Note that the return value is a late-bound region and hence wrapped in a binder.

) -> Result<Ty<'tcx>, Ty<'tcx>>
pub fn try_expand_impl_trait_type( self, def_id: DefId, args: GenericArgsRef<'tcx> ) -> Result<Ty<'tcx>, Ty<'tcx>>
Expands the given impl trait type, stopping if the type is recursive.

then
you would get a fn(u32, i32)
.
unsafety
determines the unsafety of the fn signature. If you pass

Given the def-id of an early-bound lifetime on an RPIT corresponding to
a duplicated captured lifetime, map it back to the early- or late-bound
lifetime of the function from which it originally as captured. If it is
a late-bound lifetime, this will represent the liberated (ReFree

Named module children from all kinds of items, including imports.
In addition to regular items this list also includes struct and variant constructors, and
items inside extern {}
blocks because all of them introduce names into parent module.
Module here is understood in name resolution sense - it can be a mod
item,
or a crate root, or an enum, or a trait.
This is not a query, making it a query causes perf regressions
(probably due to hashing spans in ModChild
ren).

sourcepub fn hir_crate(self, key: ()) -> &'tcx Crate<'tcx>
pub fn hir_crate(self, key: ()) -> &'tcx Crate<'tcx>
Represents crate as a whole (as distinct from the top-level crate module).
If you call hir_crate
(e.g., indirectly by calling tcx.hir().krate()
),
we will have to assume that any change means that you need to be recompiled.
This is because the hir_crate
query gives you access to all other items.

[query description - consider adding a doc-comment!] running analysis passes on this crate
sourcepub fn check_expectations(self, key: Option<Symbol>)
pub fn check_expectations(self, key: Option<Symbol>)
This query checks the fulfillment of collected lint expectations. All lint emitting queries have to be done before this is executed to ensure that all expectations can be fulfilled.
This is an extra query to enable other drivers (like rustdoc) to
only execute a small subset of the analysis
query, while allowing
lints to be expected. In rustc, this query will be executed as part of
the analysis
query and doesn’t have to be called a second time.
Tools can additionally pass in a tool filter. That will restrict the
expectations to only trigger for lints starting with the listed tool
name. This is useful for cases were not all linting code from rustc
was called. With the default None
all registered lints will also
be checked for expectation fulfillment.
sourcepub fn generics_of(self, key: impl IntoQueryParam<DefId>) -> &'tcx Generics
pub fn generics_of(self, key: impl IntoQueryParam<DefId>) -> &'tcx Generics
Maps from the DefId

sourcepub fn predicates_of(
self,
key: impl IntoQueryParam<DefId>
) -> GenericPredicates<'tcx>
pub fn predicates_of( self, key: impl IntoQueryParam<DefId> ) -> GenericPredicates<'tcx>
Maps from the DefId
of an item (trait/struct/enum/fn) to the
predicates (where-clauses) that must be proven true in order
to reference it. This is almost always the “predicates query”
that you want.
predicates_of
builds on predicates_defined_on
– in fact,
it is almost always the same as that query, except for the
case of traits. For traits, predicates_of
contains
an additional Self: Trait<...>
predicate that users don’t
actually write. This reflects the fact that to invoke the
trait (e.g., via Default::default
) you must supply types
that actually implement the trait. (However, this extra
predicate gets in the way of some checks, which are intended
to operate over only the actual where-clauses written by the
user.)

pub fn explicit_item_bounds( self, key: impl IntoQueryParam<DefId> ) -> EarlyBinder<&'tcx [(Clause<'tcx>, Span)]>
Returns the list of bounds that can be used for
SelectionCandidate::ProjectionCandidate(_)
and
ProjectionTyCandidate::TraitDef
.
Specifically this is the bounds written on the trait’s type
definition, or those after the impl
keyword
type X: Bound + 'lt
// ^^^^^^^^^^^
impl Debug + Display
// ^^^^^^^^^^^^^^^
key
is the DefId
of the associated type or opaque type.
Bounds from the parent (e.g. with nested impl trait) are not included.
sourcepub fn item_bounds(

key: impl IntoQueryParam<DefId>
) -> EarlyBinder<&'tcx List<Clause<'tcx>>>
pub fn item_bounds( self, key: impl IntoQueryParam<DefId> ) -> EarlyBinder<&'tcx List<Clause<'tcx>>>
Elaborated version of the predicates from explicit_item_bounds
.
For example:
trait MyTrait {
type MyAType: Eq + ?Sized;
}
explicit_item_bounds
returns [<Self as MyTrait>::MyAType: Eq]
,
and item_bounds
returns
[
<Self as Trait>::MyAType: Eq,
<Self as Trait>::MyAType: PartialEq<<Self as Trait>::MyAType>
]
Bounds from the parent (e.g. with nested impl trait) are not included.

pub fn closure_saved_names_of_captured_variables( self, key: impl IntoQueryParam<DefId> ) -> &'tcx IndexVec<FieldIdx, Symbol>
Returns names of captured upvars for closures and generators.
Here are some examples:
name__field1__field2
when the upvar is captured by value._ref__name__field
when the upvar is captured by reference.
For generators this only contains upvars that are shared by all states.

sourcepub fn optimized_mir(self, key: impl IntoQueryParam<DefId>) -> &'tcx Body<'tcx>
pub fn optimized_mir(self, key: impl IntoQueryParam<DefId>) -> &'tcx Body<'tcx>

pub fn covered_code_regions( self, key: impl IntoQueryParam<DefId> ) -> &'tcx Vec<&'tcx CodeRegion>
Returns the CodeRegions

key: impl IntoQueryParam<DefId>
) -> &'tcx IndexVec<Promoted, Body<'tcx>>
pub fn promoted_mir( self, key: impl IntoQueryParam<DefId> ) -> &'tcx IndexVec<Promoted, Body<'tcx>>
The DefId
is the DefId
of the containing MIR body. Promoteds do not have their own
DefId
. This function returns all promoteds in the specified body. The body references
promoteds by the DefId
and the mir::Promoted
index. This is necessary, because
after inlining a body may refer to promoteds from other bodies. In that case you still
need to use the DefId
of the original body.
sourcepub fn erase_regions_ty(self, key: Ty<'tcx>) -> Ty<'tcx>
pub fn erase_regions_ty(self, key: Ty<'tcx>) -> Ty<'tcx>
Erases regions from ty
to yield a new type.
Normally you would just use tcx.erase_regions(value)
,
however, which uses this query as a kind of cache.
sourcepub fn wasm_import_module_map(

self,
key: impl IntoQueryParam<DefId>
) -> GenericPredicates<'tcx>
pub fn predicates_defined_on( self, key: impl IntoQueryParam<DefId> ) -> GenericPredicates<'tcx>
Maps from the DefId
of an item (trait/struct/enum/fn) to the
predicates (where-clauses) directly defined on it. This is
equal to the explicit_predicates_of
predicates plus the
inferred_outlives_of
predicates.
sourcepub fn trait_explicit_predicates_and_bounds(
self,
key: impl IntoQueryParam<LocalDefId>
) -> GenericPredicates<'tcx>
pub fn trait_explicit_predicates_and_bounds( self, key: impl IntoQueryParam<LocalDefId> ) -> GenericPredicates<'tcx>
Returns everything that looks like a predicate written explicitly by the user on a trait item.
Traits are unusual, because predicates on associated types are converted into bounds on that type for backwards compatibility:
trait X where Self::U: Copy { type U; }
becomes
trait X { type U: Copy; }
explicit_predicates_of
and explicit_item_bounds
will then take
the appropriate subsets of the predicates here.
sourcepub fn explicit_predicates_of(
self,
key: impl IntoQueryParam<DefId>
) -> GenericPredicates<'tcx>
pub fn explicit_predicates_of( self, key: impl IntoQueryParam<DefId> ) -> GenericPredicates<'tcx>
Returns the predicates written explicitly by the user.
sourcepub fn inferred_outlives_of(

pub fn inferred_outlives_of( self, key: impl IntoQueryParam<DefId> ) -> &'tcx [(Clause<'tcx>, Span)]
Returns the inferred outlives predicates (e.g., for struct Foo<'a, T> { x: &'a T }
, this would return T: 'a
).

self,
key: impl IntoQueryParam<DefId>
) -> GenericPredicates<'tcx>
pub fn super_predicates_of( self, key: impl IntoQueryParam<DefId> ) -> GenericPredicates<'tcx>
Maps from the DefId
of a trait to the list of
super-predicates. This is a subset of the full list of
predicates. We store these in a separate map because we must
evaluate them even during type conversion, often before the
full predicates are available (note that supertraits have
additional acyclicity requirements).
sourcepub fn implied_predicates_of(
self,
key: impl IntoQueryParam<DefId>
) -> GenericPredicates<'tcx>
pub fn implied_predicates_of( self, key: impl IntoQueryParam<DefId> ) -> GenericPredicates<'tcx>

) -> GenericPredicates<'tcx>
pub fn super_predicates_that_define_assoc_item( self, key: (DefId, Ident) ) -> GenericPredicates<'tcx>
The Option<Ident>
is the name of an associated type. If it is None
, then this query
returns the full set of predicates. If Some<Ident>
, then the query returns only the
subset of super-predicates that reference traits that define the given associated type.
This is used to avoid cycles in resolving types like T::Item
.
sourcepub fn type_param_predicates(
self,
key: (LocalDefId, LocalDefId, Ident)
) -> GenericPredicates<'tcx>
pub fn type_param_predicates( self, key: (LocalDefId, LocalDefId, Ident) ) -> GenericPredicates<'tcx>
To avoid cycles within the predicates of a single item we compute
per-type-parameter predicates for resolving T::AssocTy
.

sourcepub fn constness(self, key: impl IntoQueryParam<DefId>) -> Constness
pub fn constness(self, key: impl IntoQueryParam<DefId>) -> Constness
Returns true
if this is a const fn, use the is_const_fn
to know whether your crate
actually sees it as const fn (e.g., the const-fn-ness might be unstable and you might
not have the feature gate active).
Do not call this function manually. It is only meant to cache the base data for the
is_const_fn
function. Consider using is_const_fn
or is_const_fn_raw
instead.
sourcepub fn asyncness(self, key: impl IntoQueryParam<DefId>) -> Asyncness
pub fn asyncness(self, key: impl IntoQueryParam<DefId>) -> Asyncness
[query description - consider adding a doc-comment!] checking if the function is async: tcx.def_path_str(key)
sourcepub fn is_promotable_const_fn(self, key: impl IntoQueryParam<DefId>) -> bool
pub fn is_promotable_const_fn(self, key: impl IntoQueryParam<DefId>) -> bool
Returns true
if calls to the function may be promoted.
This is either because the function is e.g., a tuple-struct or tuple-variant
constructor, or because it has the #[rustc_promotable]
attribute. The attribute should
be removed in the future in favour of some form of check which figures out whether the
function does not inspect the bits of any of its arguments (so is essentially just a
constructor function).
sourcepub fn generator_kind(
self,
key: impl IntoQueryParam<DefId>
) -> Option<GeneratorKind>
pub fn generator_kind( self, key: impl IntoQueryParam<DefId> ) -> Option<GeneratorKind>

sourcepub fn associated_item_def_ids(
self,
key: impl IntoQueryParam<DefId>
) -> &'tcx [DefId]
pub fn associated_item_def_ids( self, key: impl IntoQueryParam<DefId> ) -> &'tcx [DefId]
Maps from an impl/trait or struct/variant DefId
to a list of the DefId
s of its associated items or fields.

) -> &'tcx DefIdMap<DefId>
pub fn impl_item_implementor_ids( self, key: impl IntoQueryParam<DefId> ) -> &'tcx DefIdMap<DefId>
Maps from associated items on a trait to the corresponding associated
item on the impl specified by impl_id
.
For example, with the following code
struct Type {}
// DefId
trait Trait { // trait_id
fn f(); // trait_f
fn g() {} // trait_g
}
impl Trait for Type { // impl_id
fn f() {} // impl_f
fn g() {} // impl_g
}
The map returned for tcx.impl_item_implementor_ids(impl_id)
would be
{ trait_f: impl_f, trait_g: impl_g }

) -> &'tcx [DefId]
pub fn associated_types_for_impl_traits_in_associated_fn( self, key: impl IntoQueryParam<DefId> ) -> &'tcx [DefId]
Given fn_def_id
of a trait or of an impl that implements a given trait:
if fn_def_id
is the def id of a function defined inside a trait, then it creates and returns
the associated items that correspond to each impl trait in return position for that trait.
if fn_def_id

pub fn assumed_wf_types( self, key: impl IntoQueryParam<LocalDefId> ) -> &'tcx [(Ty<'tcx>, Span)]
Returns the types assumed to be well formed while “inside” of the given item.
Note that we’ve liberated the late bound regions of function signatures, so this can not be used to check whether these types are well formed.

) -> &'tcx [(Ty<'tcx>, Span)]
pub fn assumed_wf_types_for_rpitit( self, key: impl IntoQueryParam<DefId> ) -> &'tcx [(Ty<'tcx>, Span)]

sourcepub fn upstream_monomorphizations(
self,
key: ()
) -> &'tcx DefIdMap<FxHashMap<GenericArgsRef<'tcx>, CrateNum>>
pub fn upstream_monomorphizations( self, key: () ) -> &'tcx DefIdMap<FxHashMap<GenericArgsRef<'tcx>, CrateNum>>
The entire set of monomorphizations the local crate can safely link
to because they are exported from upstream crates. Do not depend on
this directly, as its value changes anytime a monomorphization gets
added or removed in any upstream crate. Instead use the narrower
upstream_monomorphizations_for
, upstream_drop_glue_for
, or, even
better, Instance::upstream_monomorphization()
.
sourcepub fn upstream_monomorphizations_for(
self,
key: impl IntoQueryParam<DefId>
) -> Option<&'tcx FxHashMap<GenericArgsRef<'tcx>, CrateNum>>
pub fn upstream_monomorphizations_for( self, key: impl IntoQueryParam<DefId> ) -> Option<&'tcx FxHashMap<GenericArgsRef<'tcx>, CrateNum>>
Returns the set of upstream monomorphizations available for the
generic function identified by the given def_id
. The query makes
sure to make a stable selection if the same monomorphization is
available in multiple upstream crates.
You likely want to call Instance::upstream_monomorphization()
instead of invoking this query directly.
sourcepub fn upstream_drop_glue_for(
self,
key: GenericArgsRef<'tcx>
) -> Option<CrateNum>
pub fn upstream_drop_glue_for( self, key: GenericArgsRef<'tcx> ) -> Option<CrateNum>
Returns the upstream crate that exports drop-glue for the given
type (args
is expected to be a single-item list containing the
type one wants drop-glue for).
This is a subset of upstream_monomorphizations_for
in order to
increase dep-tracking granularity. Otherwise adding or removing any
type with drop-glue in any upstream crate would invalidate all
functions calling drop-glue of an upstream type.
You likely want to call Instance::upstream_monomorphization()
instead of invoking this query directly.
NOTE: This query could easily be extended to also support other
common functions that have are large set of monomorphizations
(like Clone::clone
for example).

For a given item’s generic parameter, gets the default lifetimes to be used
for each parameter if a trait object were to be passed for that parameter.
For example, for T
in struct Foo<'a, T>
, this would be 'static
.
For T
in struct Foo<'a, T: 'a>
, this would instead be 'a
.
This query will panic if passed something that is not a type parameter.

sourcepub fn visibility(self, key: impl IntoQueryParam<DefId>) -> Visibility<DefId>
pub fn visibility(self, key: impl IntoQueryParam<DefId>) -> Visibility<DefId>
Computes the visibility of the provided def_id
.
If the item from the def_id
doesn’t have a visibility, it will panic. For example
a generic type parameter will panic if you call this method on it:
use std::fmt::Debug;
pub trait Foo<T: Debug> {}
In here, if you call visibility
on T
, it’ll panic.

sourcepub fn diagnostic_hir_wf_check(
self,
key: (Predicate<'tcx>, WellFormedLoc)
) -> &'tcx Option<ObligationCause<'tcx>>
pub fn diagnostic_hir_wf_check( self, key: (Predicate<'tcx>, WellFormedLoc) ) -> &'tcx Option<ObligationCause<'tcx>>
Performs an HIR-based well-formed check on the item with the given HirId
. If
we get an Unimplemented
error that matches the provided Predicate
, return
the cause of the newly created obligation.
This is only used by error-reporting code to get a better cause (in particular, a better
span) for an existing error. Therefore, it is best-effort, and may never handle
all of the cases that the normal ty::Ty
-based wfcheck does. This is fine,
because the ty::Ty
-based wfcheck is always run.
sourcepub fn global_backend_features(self, key: ()) -> &'tcx Vec<String>
pub fn global_backend_features(self, key: ()) -> &'tcx Vec<String>
The list of backend features computed from CLI flags (-Ctarget-cpu

,
--target
and similar).

) -> Result<(), NoSolution>
pub fn check_tys_might_be_eq( self, key: Canonical<'tcx, (ParamEnv<'tcx>, Ty<'tcx>, Ty<'tcx>)> ) -> Result<(), NoSolution>
Used in super_combine_consts
to ICE if the type of the two consts are definitely not going to end up being
equal to eachother. This might return Ok
even if the types are not equal, but will never return Err
if
the types might be equal.
sourcepub fn stripped_cfg_items(self, key: CrateNum) -> &'tcx [StrippedCfgItem]
pub fn stripped_cfg_items(self, key: CrateNum) -> &'tcx [StrippedCfgItem]
Get all item paths that were stripped by a #[cfg]
in a particular crate.
Should not be called for the local crate before the resolver outputs are created, as it
is only fed there.
