Struct chalk_ir::AnswerSubst

pub struct AnswerSubst<I: Interner> {
    pub subst: Substitution<I>,
    pub constraints: Constraints<I>,
    pub delayed_subgoals: Vec<InEnvironment<Goal<I>>>,
}

The resulting substitution after solving a goal.

Fields

subst: Substitution<I>

The substitution result.

NB: The is_trivial routine relies on the fact that subst is folded first.

constraints: Constraints<I>

List of constraints that are part of the answer.

delayed_subgoals: Vec<InEnvironment<Goal<I>>>

Delayed subgoals, used when the solver answered with an (incomplete) Answer (instead of a CompleteAnswer).

Trait Implementations

impl<I: Clone + Interner> Clone for AnswerSubst<I>

fn clone(&self) -> AnswerSubst<I>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<I: Debug + Interner> Debug for AnswerSubst<I>

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

Formats the value using the given formatter.

impl<I: Eq + Interner> Eq for AnswerSubst<I>

impl<I: Interner, _TI> Fold<I, _TI> for AnswerSubst<I> where
    _TI: TargetInterner<I>, 

type Result = AnswerSubst<_TI>

The type of value that will be produced once folding is done. Typically this is Self, unless Self contains borrowed values, in which case owned values are produced (for example, one can fold over a &T value where T: Fold, in which case you get back a T, not a &T).

fn fold_with<'i>(
    &self,
    folder: &mut dyn Folder<'i, I, _TI>,
    outer_binder: DebruijnIndex
) -> Fallible<Self::Result> where
    I: 'i,
    _TI: 'i, 

Apply the given folder folder to self; binders is the number of binders that are in scope when beginning the folder. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.

impl<I: Interner> HasInterner for AnswerSubst<I>

type Interner = I

The interner associated with the type.

impl<I: Hash + Interner> Hash for AnswerSubst<I>

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl<I: PartialEq + Interner> PartialEq<AnswerSubst<I>> for AnswerSubst<I>

fn eq(&self, other: &AnswerSubst<I>) -> bool

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

fn ne(&self, other: &AnswerSubst<I>) -> bool

This method tests for !=.

impl<I: Interner> StructuralEq for AnswerSubst<I>

impl<I: Interner> StructuralPartialEq for AnswerSubst<I>

impl<I: Interner> Visit<I> for AnswerSubst<I>

fn visit_with<'i, R: VisitResult>(
    &self,
    visitor: &mut dyn Visitor<'i, I, Result = R>,
    outer_binder: DebruijnIndex
) -> R where
    I: 'i, 

Apply the given visitor visitor to self; binders is the number of binders that are in scope when beginning the visitor. Typically binders starts as 0, but is adjusted when we encounter Binders<T> in the IR or other similar constructs.
