+//! Bincode is a crate for encoding and decoding using a tiny binary
+//! serialization strategy.  Using it, you can easily go from having
+//! an object in memory, quickly serialize it to bytes, and then
+//! deserialize it back just as fast!
+//!
+//! ### Using Basic Functions
+//!
+//! ```edition2018
+//! fn main() {
+//!     // The object that we will serialize.
+//!     let target: Option<String>  = Some("hello world".to_string());
+//!
+//!     let encoded: Vec<u8> = bincode::serialize(&target).unwrap();
+//!     let decoded: Option<String> = bincode::deserialize(&encoded[..]).unwrap();
+//!     assert_eq!(target, decoded);
+//! }
+//! ```
+//!
+//! ### 128bit numbers
+//!
+//! Support for `i128` and `u128` is automatically enabled on Rust toolchains
+//! greater than or equal to `1.26.0` and disabled for targets which do not support it
