Type Alias ProvidedValue

pub type ProvidedValue<'tcx> = Result<(&'tcx [Spanned<MonoItem<'tcx>>], &'tcx [Spanned<MonoItem<'tcx>>]), NormalizationErrorInMono>;

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 [Spanned<MonoItem<'tcx>>], &'tcx [Spanned<MonoItem<'tcx>>])),
    Err(NormalizationErrorInMono),
}

Variants§

§

Ok((&'tcx [Spanned<MonoItem<'tcx>>], &'tcx [Spanned<MonoItem<'tcx>>]))

Contains the success value

§

Err(NormalizationErrorInMono)

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.
