Provided Methods

fn new_projection_from_args( interner: I, def_id: I::DefId, args: I::GenericArgs, ) -> Self

fn is_known_rigid(self) -> bool

Returns true when the outermost type cannot be further normalized, resolved, or instantiated. This includes all primitive types, but also things like ADTs and trait objects, sice even if their arguments or nested types may be further simplified, the outermost ty::TyKind or type constructor remains the same.

Object Safety

This trait is not object safe.
