pub type Value<'tcx> = Result<&'tcx Canonical<'tcx, QueryResponse<'tcx, Ty<'tcx>>>, NoSolution>;

Aliased Type

enum Value<'tcx> {
    Ok(&'tcx Canonical<'tcx, QueryResponse<'tcx, Ty<'tcx>>>),
    Err(NoSolution),
}

Variants

Ok(&'tcx Canonical<'tcx, QueryResponse<'tcx, Ty<'tcx>>>)

Contains the success value

Err(NoSolution)

Contains the error value

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.
