Enum rustc_middle::traits::solve::inspect::GoalEvaluationKind

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

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.

Trait Implementations

impl<'tcx> PartialEq<GoalEvaluationKind<'tcx>> for GoalEvaluationKind<'tcx>

fn eq(&self, other: &GoalEvaluationKind<'tcx>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'tcx> Eq for GoalEvaluationKind<'tcx>

impl<'tcx> StructuralEq for GoalEvaluationKind<'tcx>

impl<'tcx> StructuralPartialEq for GoalEvaluationKind<'tcx>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
