- * Generic hashing support.
- *
- * This module provides a generic way to compute the hash of a value. The
- * simplest way to make a type hashable is to use `#[deriving(Hash)]`:
- *
- * # Example
- *
- * ```rust
- * use std::hash;
- * use std::hash::Hash;
- *
- * #[deriving(Hash)]
- * struct Person {
- *     id: uint,
- *     name: String,
- *     phone: u64,
- * }
- *
- * let person1 = Person { id: 5, name: "Janet".to_string(), phone: 555_666_7777 };
- * let person2 = Person { id: 5, name: "Bob".to_string(), phone: 555_666_7777 };
- *
- * assert!(hash::hash(&person1) != hash::hash(&person2));
- * ```
- *
- * If you need more control over how a value is hashed, you need to implement
- * the trait `Hash`:
- *
- * ```rust
- * use std::hash;
- * use std::hash::Hash;
- * use std::hash::sip::SipState;
- *
- * struct Person {
- *     id: uint,
- *     name: String,
- *     phone: u64,

- *     fn hash(&self, state: &mut SipState) {
- *         self.id.hash(state);
- *         self.phone.hash(state);
- *     }

-# The `Iterator` trait

-This module defines Rust's core iteration trait. The `Iterator` trait has one
-unimplemented method, `next`. All other methods are derived through default
-methods to perform operations such as `zip`, `chain`, `enumerate`, and `fold`.
-
-The goal of this module is to unify iteration across all containers in Rust.

-
-There are various extensions also defined in this module to assist with various
-types of iteration, such as the `DoubleEndedIterator` for iterating in reverse,
-the `FromIterator` trait for creating a container from an iterator, and much
-more.

-
-The special syntax used by rust's `for` loop is based around the `Iterator`
-trait defined in this module. For loops can be viewed as a syntactical expansion
-into a `loop`, for example, the `for` loop in this example is essentially
-translated to the `loop` below.
-
-```rust
-let values = vec![1i, 2, 3];

-// "Syntactical sugar" taking advantage of an iterator
-for &x in values.iter() {
