Struct chalk_ir::Normalize [−][src]
Expand description
Proves that the given type alias normalizes to the given
type. A projection T::Foo
normalizes to the type U
if we can
match it to an impl and that impl has a type Foo = V
where
U = V
.
Fields
alias: AliasTy<I>
ty: Ty<I>
Trait Implementations
Cast a value to type T
.
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
