Type Alias rustc_middle::query::queries::object_lifetime_default::ProvidedValue

pub type ProvidedValue<'tcx> = ObjectLifetimeDefault;

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 Deref>::Target instead.

enum ProvidedValue<'tcx> {
    Empty,
    Static,
    Ambiguous,
    Param(DefId),
}
