Module type Reins.ListIterator.S

module type S = sig .. end
The signature for an iterator over a List.

type direction_ =
| Left_Right
| Right_Left
List iterators support only two directions. Left_Right iterates through the list in the forward direction, visiting the head of the list before the tail. Right_Left is the opposite. It iterates through all elements in the tail before visiting the head.
