Trait Implementations§

source§

impl<'tcx> PartialEq for CanonicalGoalEvaluationKind<'tcx>

source§

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

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

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.
