[−][src]Struct rustc_mir::borrow_check::region_infer::RegionDefinition

pub(crate) struct RegionDefinition<'tcx> {
    pub(in borrow_check) origin: NLLRegionVariableOrigin,
    pub(in borrow_check) universe: UniverseIndex,
    pub(in borrow_check) external_name: Option<Region<'tcx>>,
}

Fields

origin: NLLRegionVariableOrigin

What kind of variable is this -- a free region? existential variable? etc. (See the NLLRegionVariableOrigin for more info.)

universe: UniverseIndex

Which universe is this region variable defined in? This is most often ty::UniverseIndex::ROOT, but when we encounter forall-quantifiers like for<'a> { 'a = 'b }, we would create the variable for 'a in a fresh universe that extends ROOT.

external_name: Option<Region<'tcx>>

If this is 'static or an early-bound region, then this is Some(X) where X is the name of the region.
