Struct GoalEvaluation

source 
pub struct GoalEvaluation<I>
where
    I: Interner,
{
    pub uncanonicalized_goal: Goal<I, <I as Interner>::Predicate>,
    pub orig_values: Vec<<I as Interner>::GenericArg>,
    pub evaluation: CanonicalGoalEvaluation<I>,
}
Expand description

When evaluating a goal 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.
