Struct SelectionCandidateSet

Source 
struct SelectionCandidateSet<'tcx> {
    vec: Vec<SelectionCandidate<'tcx>>,
    ambiguous: bool,
}

Fields§

§vec: Vec<SelectionCandidate<'tcx>>

A list of candidates that definitely apply to the current obligation (meaning: types unify).

§ambiguous: bool

If true, then there were candidates that might or might not have applied, but we couldn’t tell. This occurs when some of the input types are type variables, in which case there are various “builtin” rules that might or might not trigger.
