Struct chalk_ir::AnswerSubst [−][src]
pub struct AnswerSubst<I: Interner> { pub subst: Substitution<I>, pub constraints: Constraints<I>, pub delayed_subgoals: Vec<InEnvironment<Goal<I>>>, }
Expand description
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
).

[src]impl<I: Interner> Fold<I> for AnswerSubst<I>
[src]
impl<I: Interner> Fold<I> for AnswerSubst<I>
[src]type Result = AnswerSubst<I>
type Result = AnswerSubst<I>
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
). Read more
