Struct chalk_ir::FnPointer [−][src]
pub struct FnPointer<I: Interner> { pub num_binders: usize, pub sig: FnSig<I>, pub substitution: FnSubst<I>, }
Expand description
for<’a…’z> X – all binders are instantiated at once,
and we use deBruijn indices within self.ty
Fields
num_binders: usize
sig: FnSig<I>
substitution: FnSubst<I>
Implementations
Represent the current Fn
as if it was wrapped in Binders

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
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

Shifts this term in one level of binders.
Shifts a term valid at outer_binder
so that it is
valid at the innermost binder. See DebruijnIndex::shifted_in_from
