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

enum BuiltinImplConditions<'tcx> {
    Where(Binder<'tcx, Vec<Ty<'tcx>>>),
    None,
    Ambiguous,
}
Expand description

When does the builtin impl for T: Trait apply?

Variants

Where(Binder<'tcx, Vec<Ty<'tcx>>>)
Expand description

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

None
Expand description

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

Ambiguous
Expand description

It is unknown whether there is an impl.
