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.

impl<'tcx> Debug for GenericPredicates<'tcx>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

Derived Implementations

impl<'tcx> Clone for GenericPredicates<'tcx>

fn clone(&self) -> GenericPredicates<'tcx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
