Type Alias ProvidedValue

pub type ProvidedValue<'tcx> = Result<&'tcx DefIdMap<EarlyBinder<'tcx, Ty<'tcx>>>, ErrorGuaranteed>;

Expand description

This type alias specifies the type returned from query providers and the type used for decoding. For regular queries this is the declared returned type V, but arena_cache will use <V as ArenaCached>::Provided instead.

Aliased Type§

pub enum ProvidedValue<'tcx> {
    Ok(&'tcx UnordMap<DefId, EarlyBinder<TyCtxt<'tcx>, Ty<'tcx>>>),
    Err(ErrorGuaranteed),
}

Variants§

§

Ok(&'tcx UnordMap<DefId, EarlyBinder<TyCtxt<'tcx>, Ty<'tcx>>>)

Contains the success value

§

Err(ErrorGuaranteed)

Contains the error value

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
