[−][src]Enum rustc_trait_selection::traits::project::ProjectionTyCandidate

pub(in traits::project) enum ProjectionTyCandidate<'tcx> {
    ParamEnv(PolyProjectionPredicate<'tcx>),
    TraitDef(PolyProjectionPredicate<'tcx>),
    Object(PolyProjectionPredicate<'tcx>),
    Select(Selection<'tcx>),
}

Variants

ParamEnv(PolyProjectionPredicate<'tcx>)

From a where-clause in the env or object type

TraitDef(PolyProjectionPredicate<'tcx>)

From the definition of Trait when you have something like <::B as Trait2>::C

Object(PolyProjectionPredicate<'tcx>)

Bounds specified on an object type

Select(Selection<'tcx>)

From a "impl" (or a "pseudo-impl" returned by select)
