type Result = Mutability
type Result = Mutability
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

pub fn fold_with<'i>(

I: '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. Read more

Apply the given visitor visitor

is the
number of binders that are in scope when beginning the
visitor. Typically binders

pub fn zip_with<'i, Z>(
_zipper: &mut Z,
_variance: Variance,
a: &Mutability,
b: &Mutability
) -> Result<(), NoSolution> where
I: 'i,
Z: Zipper<'i, I>,
pub fn zip_with<'i, Z>(
_zipper: &mut Z,
_variance: Variance,
a: &Mutability,
b: &Mutability
) -> Result<(), NoSolution> where
I: 'i,
Z: Zipper<'i, I>,
Uses the zipper to walk through two values, ensuring that they match.

fn cast<U>(self, interner: &<U as HasInterner>::Interner) -> U where
Self: CastTo<U>,
U: HasInterner,
fn cast<U>(self, interner: &<U as HasInterner>::Interner) -> U where
Self: CastTo<U>,
U: HasInterner,
Cast a value to type U
using CastTo
.
Compare self to key
and return true
if they are equal.

Shifts this term in one level of binders.

self,
interner: &I,

) -> <T as Fold<I>>::Result
pub fn shifted_in_from(
self,
interner: &I,
source_binder: DebruijnIndex
) -> <T as Fold<I>>::Result
Shifts a term valid at outer_binder
so that it is
valid at the innermost binder. See DebruijnIndex::shifted_in_from
for a detailed explanation. Read more

pub fn shifted_out_to(
self,
interner: &I,
target_binder: DebruijnIndex
) -> Result<<T as Fold<I>>::Result, NoSolution>
Shifts a term valid at the innermost binder so that it is
valid at outer_binder
. See DebruijnIndex::shifted_out_to
for a detailed explanation. Read more
