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