pub struct LateParamRegion {
pub scope: DefId,
pub bound_region: BoundRegionKind,
}
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.
