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.

impl<'tcx> Debug for TraitPredicate<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> Display for TraitPredicate<'tcx>

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

Formats the value using the given formatter.

Derived Implementations

impl<'tcx> Hash for TraitPredicate<'tcx>

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher

Feeds a slice of this type into the state provided.

impl<'tcx> Eq for TraitPredicate<'tcx>

impl<'tcx> PartialEq for TraitPredicate<'tcx>

fn eq(&self, __arg_0: &TraitPredicate<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &TraitPredicate<'tcx>) -> bool

This method tests for !=.

impl<'tcx> Clone for TraitPredicate<'tcx>

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

Returns a copy of the value.

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

Performs copy-assignment from source.
