A library that provides ASCII-only string and character types, equivalent to the char, str and
String types in the standard library.
Types and conversion traits are described in the Documentation
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.
The ascii library requires rustc 1.9.0 or greater, due to the
stabilization of AsciiExt. Using the no_std
feature lowers this requirement to rustc 1.6.0 or greater.
This packages included the Ascii types that were removed from the Rust standard library by the
2014-12 [reform of the std::ascii module] (rust-lang/rfcs#486). The API
changed significantly since then.
