Required Methods

fn new_bound( interner: I, debruijn: DebruijnIndex, var: <I as Interner>::BoundRegion, ) -> Self

fn new_anon_bound(interner: I, debruijn: DebruijnIndex, var: BoundVar) -> Self

fn new_static(interner: I) -> Self

fn new_placeholder(interner: I, var: <I as Interner>::PlaceholderRegion) -> Self

Provided Methods

fn is_bound(self) -> bool

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.
