Expand description
Identifies a particular impl in the source, along with a set of
substitutions from the impl’s type/lifetime parameters. The
nested
vector corresponds to the nested obligations attached to
the impl’s type parameters.
The type parameter N
indicates the type used for “nested
obligations” that are required by the impl. During type-check, this
is Obligation
, as one might expect. During codegen, however, this
is ()
, because codegen only requires a shallow resolution of an
impl, and nested obligations are satisfied later.

source§fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool
fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool
true
if self
has any late-bound regions that are either
bound by binder
or bound by some binder outside of binder
.
If binder
is ty::INNERMOST
, this indicates whether
there are any late-bound regions that appear free. Read moresource§fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool

if this type has any regions that escape binder
(and
hence are not bound by it). Read moresource§fn has_escaping_bound_vars(&self) -> bool
fn has_escaping_bound_vars(&self) -> bool
true
if this type has regions that are not a part of the type.
For example, for<'a> fn(&'a i32)
return false
, while fn(&'a i32)
would return true
. The latter can occur when traversing through the
former. Read morefn has_type_flags(&self, flags: TypeFlags) -> bool

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 moresource§impl<T, R> InternIteratorElement<T, R> for T

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
