pub type ProvidedValue<'tcx> = ConstQualifs;
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 Deref>::Target instead.

Aliased Type§

struct ProvidedValue<'tcx> {
    pub has_mut_interior: bool,
    pub needs_drop: bool,
    pub needs_non_const_drop: bool,
    pub custom_eq: bool,
    pub tainted_by_errors: Option<ErrorGuaranteed>,
}
