Required Methods

fn principal_def_id(self) -> Option<<I as Interner>::DefId>

fn principal(self) -> Option<Binder<I, ExistentialTraitRef<I>>>

fn auto_traits(self) -> impl IntoIterator<Item = <I as Interner>::DefId>

fn projection_bounds( self, ) -> impl IntoIterator<Item = Binder<I, ExistentialProjection<I>>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
