Struct rustc_middle::ty::print::TraitRefPrintOnlyTraitName
source · pub struct TraitRefPrintOnlyTraitName<'tcx>(TraitRef<'tcx>);Expand description
Wrapper type for ty::TraitRef which opts-in to pretty printing only
the trait name. That is, it will print Trait instead of
<T as Trait<U>>.

source§fn has_vars_bound_at_or_above(&self, binder: DebruijnIndex) -> bool
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
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
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 morefn has_type_flags(&self, flags: TypeFlags) -> bool

source§fn has_free_regions(&self) -> bool
fn has_free_regions(&self) -> bool
“Free” regions in this context means that it has any region
that is not (a) erased or (b) late-bound.

fn has_erasable_regions(&self) -> bool
True if there are any un-erased free regions.

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.

True if there are any late-bound variables
source§fn still_further_specializable(&self) -> bool
fn still_further_specializable(&self) -> bool
Indicates whether this value still has parameters/placeholders/inference variables
which could be replaced later, in a way that would change the results of

Layout§
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.
