Iterators which split strings on Grapheme Cluster or Word boundaries, according to the Unicode Standard Annex #29 rules.

unicode-segmentation does not depend on libstd, so it can be used in crates with the #![no_std]
attribute.
You can use this package in your project by adding the following to your Cargo.toml
:
[dependencies] unicode-segmentation = "1.3.0"
GraphemeCursor
API allows random access and bidirectional iteration.as_str
methods to the iterator types.
