that points to the beginning of the Allocation
.

1.0.0 · sourcefn le(&self, other: &Rhs) -> bool
fn le(&self, other: &Rhs) -> bool
This method tests less than or equal to (for
self
and other
) and is used by the <=
operator. Read moresourceimpl Provenance for AllocId
impl Provenance for AllocId
sourceconst OFFSET_IS_ADDR: bool = false
const OFFSET_IS_ADDR: bool = false
Says whether the
offset
field of Pointer
s with this provenance is the actual physical address. Read moresourceconst ERR_ON_PARTIAL_PTR_OVERWRITE: bool = true
const ERR_ON_PARTIAL_PTR_OVERWRITE: bool = true
We also use this trait to control whether to abort execution when a pointer is being partially overwritten
(this avoids a separate trait in
allocation.rs
just for this purpose). Read moresourcefn fmt(ptr: &Pointer<Self>, f: &mut Formatter<'_>) -> Result
fn fmt(ptr: &Pointer<Self>, f: &mut Formatter<'_>) -> Result
Determines how a pointer should be printed.
sourcefn get_alloc_id(self) -> Option<AllocId>
fn get_alloc_id(self) -> Option<AllocId>
If
OFFSET_IS_ADDR == false
, provenance must always be able to
identify the allocation this ptr points to (i.e., this must return Some
).
Otherwise this function is best-effort (but must agree with Machine::ptr_get_alloc
).
(Identifying the offset in that allocation, however, is harder – use Memory::ptr_get_alloc
for that.) Read moreimpl Copy for AllocId

default fn fingerprint_style() -> FingerprintStyle
sourcedefault fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint
default fn to_fingerprint(&self, tcx: Ctxt) -> Fingerprint
This method turns the parameters of a DepNodeConstructor into an opaque
Fingerprint to be used in DepNode.
Not all DepNodeParams support being turned into a Fingerprint (they
don’t need to if the corresponding DepNode is anonymous). Read more

sourcedefault fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> Option<T>
default fn recover(Ctxt, &DepNode<<Ctxt as DepContext>::DepKind>) -> Option<T>
This method tries to recover the query key from the given
DepNode
,
something which is needed when forcing DepNode
s during red-green
evaluation. The query system will only call this method if
fingerprint_style()
is not FingerprintStyle::Opaque
.
It is always valid to return None
here, in which case incremental
compilation will treat the query as having changed instead of forcing it. Read moresourceimpl<T, R> InternIteratorElement<T, R> for T
