impl<'tcx> PartialEq<GenericKind<'tcx>> for GenericKind<'tcx>

source§

fn eq(&self, other: &GenericKind<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

source§

fn try_fold_with<__F: FallibleTypeFolder<'tcx>>(
self,
__folder: &mut __F
) -> Result<Self, __F::Error>

source§

fn fold_with<F>(self, folder: &mut F) -> Selfwhere
F: TypeFolder<'tcx>,

A convenient alternative to try_fold_with for use with infallible folders. Do not override this method, to ensure coherence with try_fold_with.

fn visit_with<__V: TypeVisitor<'tcx>>(
&self,
__visitor: &mut __V

source§

fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool

Returns 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.
source§

fn has_vars_bound_above(&self, binder: DebruijnIndex) -> bool

Returns true if this type has any regions that escape binder (and hence are not bound by it).
source§

fn has_escaping_bound_vars(&self) -> bool

Return 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 more

source§

fn has_erased_regions(&self) -> bool

source§

fn has_erasable_regions(&self) -> bool

True if there are any un-erased free regions.
source§

fn is_global(&self) -> bool

Indicates whether this value references only ‘global’ generic parameters that are the same regardless of what fn we are in. This is used for caching.
source§

fn has_late_bound_regions(&self) -> bool

True if there are any late-bound regions
source§

fn has_non_region_late_bound(&self) -> bool

True if there are any late-bound non-region variables
