/// ## Prefix collisions
///
/// Implementations of `hash` should ensure that the data they
/// pass to the `Hasher` are prefix-free. That is, different concatenations
/// of the same data should not produce the same output.
/// pass to the `Hasher` are prefix-free. That is,
/// unequal values should cause two different byte sequences to be written,
/// and neither of the two sequences should be a prefix of the other.
///
/// For example, the standard implementation of [`Hash` for `&str`][impl] passes an extra
/// `0xFF` byte to the `Hasher` so that the values `("ab", "c")` and `("a",
/// "bc")` hash differently.
