&self,
f: impl FnMut(&[BoundVariableKinds], HoleKind) -> Expr,
) -> Self
fn replace_holes( &self, f: impl FnMut(&[BoundVariableKinds], HoleKind) -> Expr, ) -> Self
Replaces all holes with the result of calling a closure. The closure takes a list with
all the layers of bound variables at the point the hole was found. Each layer corresponds
to the list of bound variables at that level. The list is ordered from outermost to innermost
binder, i.e., the last element is the binder closest to the hole.
Source§fn with_holes(&self) -> Self
fn with_holes(&self) -> Self
Remove all refinements and turn each underlying
BaseTy
into a TyKind::Exists
with a
TyKind::Constr
and a hole
. For example, Vec<{v. i32[v] | v > 0}>[n]
becomes
{n. Vec<{v. i32[v] | *}>[n] | *}

fn has_escaping_bvars_at_or_above(&self, binder: DebruijnIndex) -> bool
Returns
true
if self
has any late-bound vars that are either
bound by binder
or bound by some binder outside of binder
.
If binder
is ty::INNERMOST
, this indicates whether
there are any late-bound vars that appear free.impl Eq for ProjectionPredicate
