Type Alias ProvidedValue

Source
pub type ProvidedValue<'tcx> = ParamEnv<'tcx>;
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§

struct ProvidedValue<'tcx> {
    caller_bounds: &'tcx RawList<TypeInfo, Clause<'tcx>>,
}

Fields§

§caller_bounds: &'tcx RawList<TypeInfo, Clause<'tcx>>

Caller bounds are Obligations that the caller must satisfy. This is basically the set of bounds on the in-scope type parameters, translated into Obligations, and elaborated and normalized.

Use the caller_bounds() method to access.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
