ProvidedValue

rustc_middle::query::queries::opaque_ty_origin

Type Alias ProvidedValue 

Source 
pub type ProvidedValue<'tcx> = OpaqueTyOrigin<DefId>;
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> {
    FnReturn {
        parent: DefId,
        in_trait_or_impl: Option<RpitContext>,
    },
    AsyncFn {
        parent: DefId,
        in_trait_or_impl: Option<RpitContext>,
    },
    TyAlias {
        parent: DefId,
        in_assoc_ty: bool,
    },
}

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.
