Struct OverlapResult

source 
pub struct OverlapResult<'tcx> {
    pub impl_header: ImplHeader<'tcx>,
    pub intercrate_ambiguity_causes: FxIndexSet<IntercrateAmbiguityCause<'tcx>>,
    pub involves_placeholder: bool,

}

Fields§

§impl_header: ImplHeader<'tcx>§intercrate_ambiguity_causes: FxIndexSet<IntercrateAmbiguityCause<'tcx>>§involves_placeholder: bool

true if the overlap might’ve been permitted before the shift to universes.

§overflowing_predicates: Vec<Predicate<'tcx>>

Used in the new solver to suggest increasing the recursion limit.
