Struct GoalEvaluation 

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 final_revision: <I as Interner>::Probe,
    pub result: Result<Canonical<I, Response<I>>, NoSolution>,
}

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.

Fields

uncanonicalized_goal: Goal<I, <I as Interner>::Predicate>

orig_values: Vec<<I as Interner>::GenericArg>

final_revision: <I as Interner>::Probe

result: Result<Canonical<I, Response<I>>, NoSolution>

Trait Implementations

impl<I> Hash for GoalEvaluation<I>

where I: Interner,

fn hash<__H>(&self, __state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<I> PartialEq for GoalEvaluation<I>

where I: Interner,

fn eq(&self, __other: &GoalEvaluation<I>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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