Expand description
“Lift” and convert an impl LendingIterator
into an
impl HKT
.
type HKTItem<I : LendingIterator> = HKT!(Item<'_, I>);
- It is therefore a
CanonicalHKT
(no need to apply it again).
The main property of this alias, and thus the connection between
impl LendingIterator
s and impl HKT
,
is that:
// Given some `<'n, I : LendingIterator>`:
Apply!(HKTItem<I><'n>) = Feed<'n, HKT!(Item<'_, T>)> = Item<'n, I>
