Type Alias ProvidedValue

pub type ProvidedValue<'tcx> = Option<ScalarInt>;

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(ScalarInt),
}

Variants

None

No value.

Some(ScalarInt)

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.
