//! # uX_serde - non-standard-width integers types
//!
//! When non-standard-width integers is required in an applications, the norm is to use a larger container and make sure the value is within range after manipulation. uX_serde aims to take care of this once and for all by:
//!
//! - Providing `u1`-`u127` and `i1`-`i127` types that should behave as similar as possible to the built in rust types
//!     - The methods of the defined types are the same as for the built in types (far from all is implemented at this point but fill out an issue or create a PR if something essential for you is missing)
//!     - Overflow will panic in debug and wrap in release.
//! - All possible lossless conversions is possible by using `From`.
//! - When `TryFrom` is stabilized fallible conversions will also be supported.
