Struct rustc_infer::traits::ChalkEnvironmentAndGoal

pub struct ChalkEnvironmentAndGoal<'tcx> {
    pub environment: &'tcx List<ChalkEnvironmentClause<'tcx>>,
    pub goal: Predicate<'tcx>,
}

We have to elaborate the environment of a chalk goal before canonicalization. This type wraps the predicate and the elaborated environment.

Fields

environment: &'tcx List<ChalkEnvironmentClause<'tcx>>

goal: Predicate<'tcx>
