|

|
|
//! This crate provides a collection of Unicode-related functionality,
|
||
|
|
//! including decompositions, conversions, etc., and provides traits
|

|
|
//! implementing these functions for the `char` and `str` types.
|

|
|
//!
|
||
|
|
//! The functionality included here is only that which is necessary to
|
||
|
|
//! provide for basic string-related manipulations. This crate does not
|
||
|
|
//! (yet) aim to provide a full set of Unicode tables.
