    //! An implementation of the [Fowler–Noll–Vo hash function][chongo].
    //!
    //! ## About
    //!
    //! The FNV hash function is a custom `Hasher` implementation that is more
    //! efficient for smaller hash keys.
    //!
    //! [The Rust FAQ states that][faq] while the default `Hasher` implementation,
    //! SipHash, is good in many cases, it is notably slower than other algorithms
    //! with short keys, such as when you have a map of integers to other values.
    //! In cases like these, [FNV is demonstrably faster][graphs].
    //!
    //! Its disadvantages are that it performs badly on larger inputs, and
    //! provides no protection against collision attacks, where a malicious user
    //! can craft specific keys designed to slow a hasher down. Thus, it is
    //! important to profile your program to ensure that you are using small hash
    //! keys, and be certain that your program could not be exposed to malicious
    //! inputs (including being a networked server).
    //!
    //! The Rust compiler itself uses FNV, as it is not worried about
    //! denial-of-service attacks, and can assume that its inputs are going to be
    //! small—a perfect use case for FNV.
    //!
    #![cfg_attr(feature = "std", doc = r#"

    ## Using FNV in a `HashMap`

    The `FnvHashMap` type alias is the easiest way to use the standard library’s
    `HashMap` with FNV.

    ```rust
    use fnv::FnvHashMap;

    let mut map = FnvHashMap::default();
    map.insert(1, "one");
    map.insert(2, "two");

    map = FnvHashMap::with_capacity_and_hasher(10, Default::default());
    map.insert(1, "one");
    map.insert(2, "two");
    ```

    Note, the standard library’s `HashMap::new` and `HashMap::with_capacity`
    are only implemented for the `RandomState` hasher, so using `Default` to
    get the hasher is the next best option.

    ## Using FNV in a `HashSet`

    Similarly, `FnvHashSet` is a type alias for the standard library’s `HashSet`
    with FNV.

    ```rust
    use fnv::FnvHashSet;

    let mut set = FnvHashSet::default();
    set.insert(1);
    set.insert(2);

    set = FnvHashSet::with_capacity_and_hasher(10, Default::default());
    set.insert(1);
    set.insert(2);
    ```
