 ## Container iterators
 
 Containers implement iteration over the contained elements by returning an
 iterator object. For example, vector slices several iterators available:
 
 * `iter()` and `rev_iter()`, for immutable references to the elements
 * `mut_iter()` and `mut_rev_iter()`, for mutable references to the elements
-* `move_iter()` and `move_rev_iter()`, to move the elements out by-value
+* `move_iter()` and `move_rev_iter`, to move the elements out by-value
 
 A typical mutable container will implement at least `iter()`, `mut_iter()` and
 `move_iter()` along with the reverse variants if it maintains an order.
