Struct rustc::infer::resolve::OpportunisticTypeAndRegionResolver

pub struct OpportunisticTypeAndRegionResolver<'a, 'gcx: 'a + 'tcx, 'tcx: 'a> {
    // some fields omitted
}

Unstable (rustc_private)

[−] Expand description

The opportunistic type and region resolver is similar to the opportunistic type resolver, but also opportunistly resolves regions. It is useful for canonicalization.
