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. ### Freezing |
