float-pigment-consistent-bincode 0.9.0

#![no_std]
#![allow(clippy::legacy_numeric_constants)]
#![allow(clippy::multiple_bound_locations)]

//! 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 test() {
//!     // The object that we will serialize.
//!     let target: Option<String>  = Some("hello world".to_string());
//!
//!     let encoded: Vec<u8> = float_pigment_consistent_bincode::serialize(&target).unwrap();
//!     let decoded: Option<String> = float_pigment_consistent_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
