Enum rustc_infer::traits::solve::inspect::GoalEvaluationKind

source · 
pub enum GoalEvaluationKind<'tcx> {
    Root {
        orig_values: Vec<GenericArg<'tcx>>,
    },
    Nested {
        is_normalizes_to_hack: IsNormalizesToHack,
    },
}
Expand description

When evaluating the root goals we also store the original values for the CanonicalVarValues of the canonicalized goal. We use this to map any CanonicalState from the local InferCtxt of the solver query to the InferCtxt of the caller.
