impl<'tcx> MatchAgainstHigherRankedOutlives<'tcx>
sourcefn no_match<T>(&self) -> RelateResult<'tcx, T>
fn no_match<T>(&self) -> RelateResult<'tcx, T>
Creates the “Error” variant that signals “no match”.
sourcefn bind(
&mut self,
br: BoundRegion,
value: Region<'tcx>
) -> RelateResult<'tcx, Region<'tcx>>
fn bind( &mut self, br: BoundRegion, value: Region<'tcx> ) -> RelateResult<'tcx, Region<'tcx>>
Binds the pattern variable br
to value
; returns an Err
if the pattern
is already bound to a different value.

Relate the two args for the given item. The default
is to look up the variance for the item and proceed
accordingly.
