Provided Methods§

source

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

source

fn new_projection( interner: I, def_id: <I as Interner>::DefId, args: impl IntoIterator>, ) -> Self

source

fn is_ty_var(self) -> bool

source

fn is_floating_point(self) -> bool

source

fn is_integral(self) -> bool

source

fn is_fn_ptr(self) -> bool

source

fn fn_sig(self, interner: I) -> Binder<I, FnSig<I>>

source

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.
