Type Alias ProvidedValue 

pub type ProvidedValue<'tcx> = Option<&'tcx FxIndexSet<ItemLocalId>>;

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> {
    None,
    Some(&'tcx IndexSet<ItemLocalId, BuildHasherDefault<FxHasher>>),
}

Variants

None

No value.

Some(&'tcx IndexSet<ItemLocalId, BuildHasherDefault<FxHasher>>)

Some value of type T.

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.
