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).
Trait Implementations
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
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. Read more
type Interner = I
type Interner = I
The interner associated with the type.
This method tests for self and other values to be equal, and is used
by ==. Read more
This method tests for !=.
