Enum rustc_next_trait_solver::solve::inspect::GoalEvaluationKind

pub enum GoalEvaluationKind<I>
where
    I: Interner,
{
    Root {
        orig_values: Vec<<I as Interner>::GenericArg>,
    },
    Nested,
}

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<I> Debug for GoalEvaluationKind<I>

where I: Interner,

fn fmt(&self, __f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<I> Hash for GoalEvaluationKind<I>

where I: Interner,

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

where __HI: 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 GoalEvaluationKind<I>

where I: Interner,

fn eq(&self, other: &GoalEvaluationKind<I>) -> 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<I> Eq for GoalEvaluationKind<I>

where I: Interner,

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.
