Required Methods

fn instantiate_supertrait( self, cx: I, trait_ref: Binder<I, TraitRef<I>>, ) -> Self

Performs a instantiation suitable for going from a poly-trait-ref to supertraits that must hold if that poly-trait-ref holds. This is slightly different from a normal instantiation in terms of what happens with bound regions.

Provided Methods

fn as_trait_clause(self) -> Option<Binder<I, TraitPredicate<I>>>

fn as_projection_clause(self) -> Option<Binder<I, ProjectionPredicate<I>>>

Object Safety

This trait is not object safe.
