[−][src]Struct rustc_infer::infer::resolve::OpportunisticRegionResolver

pub struct OpportunisticRegionResolver<'a, 'tcx> {
    infcx: &'a InferCtxt<'a, 'tcx>,
}

The opportunistic region resolver opportunistically resolves regions variables to the variable with the least variable id. It is used when normlizing projections to avoid hitting the recursion limit by creating many versions of a predicate for types that in the end have to unify.

If you want to resolve type and const variables as well, call InferCtxt::resolve_vars_if_possible first.
