Trait Implementations
sourceimpl<I: Interner> Fold<I> for FnPointer<I>
impl<I: Interner> Fold<I> for FnPointer<I>
type Result = FnPointer<I>
type Result = FnPointer<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

) -> Result<Self::Result, E>
fn fold_with<E>(
self,
folder: &mut dyn Folder<I, Error = E>,
outer_binder: DebruijnIndex
) -> Result<Self::Result, E>
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
