Struct rustc_trait_selection::infer::canonical::ir::solve::inspect::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.
