//! A library that provides ASCII-only string and character types, equivalent to the `char`, `str` and
//! `String` types in the standard library.
//!
//! # Using ascii without libstd
//!
//! Most of `AsciiChar` and `AsciiStr` can be used without `std` by enabling the feature `no_std`. The
//! owned string type `AsciiString` and the conversion trait `IntoAsciiString` as well as all methods
//! referring to these types aren't available without `std`.
//!
//! # Requirements
//!
//! The `ascii` library requires rustc 1.9.0 or greater, due to the [stabilization of
//! `AsciiExt`](https://github.com/rust-lang/rust/pull/32804). Using the `no_std` feature lowers
//! this requirement to rustc 1.6.0 or greater.
//!
//! # History
//!
//! This packages 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.
