//! A library that provides ASCII-only string and character types, equivalent to the `char`, `str`
//! and `String` types in the standard library.
//!
//! Please refer to the readme file to learn about the different feature modes of this crate.
//!
//! # Minimum supported Rust version
//!
//! The minimum Rust version for 1.0.\* releases is 1.33.0.
//! Later 1.y.0 releases might require newer Rust versions, but the three most
//! recent stable releases at the time of publishing will always be supported.  
//! For example this means that if the current stable Rust version is 1.38 when
//! ascii 1.1.0 is released, then ascii 1.1.* will not require a newer
//! Rust version than 1.36.
//!
//! # History
//!
//! This package included the Ascii types that were removed from the Rust standard library by the
//! 2014-12 [reform of the `std::ascii` module](https://github.com/rust-lang/rfcs/pull/486). The
//! API changed significantly since then.
