[−][src]Enum rustc_trait_selection::traits::select::BuiltinImplConditions

pub(in traits::select) enum BuiltinImplConditions<'tcx> {
    Where(Binder<Vec<Ty<'tcx>>>),
    None,
    Ambiguous,
}

When does the builtin impl for T: Trait apply?

Variants

Where(Binder<Vec<Ty<'tcx>>>)

The impl is conditional on T1, T2, ...: Trait.

None

There is no built-in impl. There may be some other candidate (a where-clause or user-defined impl).

Ambiguous

It is unknown whether there is an impl.
