#![deny(missing_docs)]
#![allow(unknown_lints, bare_trait_objects, deprecated)]
//! 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
