Struct chalk_ir::ConstrainedSubst
source · [−]pub struct ConstrainedSubst<I: Interner> {
pub subst: Substitution<I>,
pub constraints: Constraints<I>,
}
Expand description
Combines a substitution (subst
) with a set of region constraints
(constraints
). This represents the result of a query; the
substitution stores the values for the query’s unknown variables,
and the constraints represents any region constraints that must
additionally be solved.
Fields
subst: Substitution<I>
The substitution that is being constrained.
NB: The is_trivial
routine relies on the fact that subst
is folded first.
constraints: Constraints<I>
Region constraints that constrain the substitution.

impl<I: Interner> Fold<I> for ConstrainedSubst<I>
type Result = ConstrainedSubst<I>
type Result = ConstrainedSubst<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
