-//! However, due to limitations of safe Rust, hashing takes only the data address into account.
-//! **This may cause performance problems if you use slices as keys in a by-address HashMap or
-//! HashSet.**  It won't cause correctness bugs, but it may cause a high rate of hash collisions if
-//! the keys include many slices with the same starting points but different lengths.
-//!
-//! ```
-//! # use by_address::ByAddress;
-//! # use std::collections::hash_map::DefaultHasher;
-//! # use std::hash::{Hash, Hasher};
-//! #
-//! fn hash<T: Hash>(t: T) -> u64 {
-//!     let mut s = DefaultHasher::new();
-//!     t.hash(&mut s);
-//!     s.finish()
-//! }
-//!
-//! let v = [1, 2, 3, 4];
-//! assert_eq!(hash(ByAddress(&v[0..4])),
-//!            hash(ByAddress(&v[0..2]))); // Uh-oh!
-//! ```

 //! This crate does not depend on libstd, so it can be used in [`no_std`] projects.
