Required Methods§

source

fn has_type_flags(&self, flags: TypeFlags) -> bool

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 error_reported(&self) -> Result<(), <I as Interner>::ErrorGuaranteed>

Provided Methods§

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.

See HasEscapingVarsVisitor for more information.

source

fn has_aliases(&self) -> bool

source

fn has_opaque_types(&self) -> bool

source

fn has_coroutines(&self) -> bool

source

fn references_error(&self) -> bool

source

fn has_non_region_param(&self) -> bool

source

fn has_infer_regions(&self) -> bool

source

fn has_infer_types(&self) -> bool

source

fn has_non_region_infer(&self) -> bool

source

fn has_infer(&self) -> bool

source

fn has_placeholders(&self) -> bool

source

fn has_non_region_placeholders(&self) -> bool

source

fn has_param(&self) -> bool

source

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.

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_bound_regions(&self) -> bool

True if there are any late-bound regions

source

fn has_non_region_bound_vars(&self) -> bool

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

source

fn has_bound_vars(&self) -> bool

True if there are any bound variables

source

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 impl specialization.

Object Safety§

This trait is not object safe.
