pub struct LateParamRegion {
pub scope: DefId,
pub kind: LateParamRegionKind,
}
Expand description
The parameter representation of late-bound function parameters, “some region
at least as big as the scope fr.scope
”.
Similar to a placeholder region as we create LateParam
regions when entering a binder
except they are always in the root universe and instead of using a boundvar to distinguish
between others we use the DefId
of the parameter. For this reason the bound_region
field
should basically always be BoundRegionKind::Named
as otherwise there is no way of telling
different parameters apart.

It is always valid to return None
here, in which case incremental
compilation will treat the query as having changed instead of forcing it.Source§impl<Q, K> Equivalent<K> for Q
