Struct ra_ap_hir_ty::FnSubst [−][src]
pub struct FnSubst<I>(pub Substitution<I>)
where
I: Interner;
Expand description
A wrapper for the substs on a Fn.
Trait Implementations
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>(
self,
folder: &mut dyn Folder<'i, I>,
outer_binder: DebruijnIndex
) -> Result<<FnSubst<I> as Fold<I>>::Result, NoSolution> where
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
type Interner = I
type Interner = I
The interner associated with the type.

pub fn visit_with<'i, B>(

I: 'i,
Apply the given visitor visitor
to self
; binders
is the
number of binders that are in scope when beginning the
visitor. Typically binders
starts as 0, but is adjusted when
we encounter Binders<T>
in the IR or other similar

impl<T, I> CouldMatch<T> for T where
T: Zip<I> + HasInterner<Interner = I> + ?Sized,
I: Interner,
Checks whether self
and other

Compare self to key
and return true
if they are equal.
Instruments this type with the provided Span
, returning an
Instrumented

Shifts this term in one level of binders.
pub fn shifted_in_from(
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

interner: &I,
target_binder: DebruijnIndex

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
Shifts this term out one level of binders.
Check whether there are free (non-bound) variables.
