fn needs_infer(&self) -> bool

fn needs_subst(&self) -> bool

fn has_closure_types(&self) -> bool

fn has_erasable_regions(&self) -> bool

fn is_global(&self) -> bool

Indicates whether this value references only 'global' types/lifetimes that are the same regardless of what fn we are in. This is used for caching. Errs on the side of returning false.
