Trait Implementations

impl<'tcx, T> QueryTypeOp<'tcx> for Normalize<T> where
    T: Normalizable<'tcx> + 'tcx, [src]

type QueryResponse = T

fn try_fast_path(_tcx: TyCtxt<'tcx>, key: &ParamEnvAnd<'tcx, Self>) -> Option<T>[src]

Give query the option for a simple fast path that never actually hits the tcx cache lookup etc. Return Some(r) with a final result or None to do the full path. Read more

fn perform_query(
    tcx: TyCtxt<'tcx>,
    canonicalized: Canonicalized<'tcx, ParamEnvAnd<'tcx, Self>>
) -> Fallible<CanonicalizedQueryResponse<'tcx, Self::QueryResponse>>[src]

Performs the actual query with the canonicalized key – the real work happens here. This method is not given an infcx because it shouldn’t need one – and if it had access to one, it might do things like invoke sub_regions, which would be bad, because it would create subregion relationships that are not captured in the return value.

    query_key: ParamEnvAnd<'tcx, Self>,
    infcx: &InferCtxt<'_, 'tcx>,
