unicode-segmentation does not depend on libstd, so it can be used in crateswith the#![no_std] attribute.
You can use this package in your project by adding the followingto yourCargo.toml:
[dependencies]unicode-segmentation = "1.7.1"| GraphemeCursor | Cursor-based segmenter for grapheme clusters. |
| GraphemeIndices | External iterator for grapheme clusters and byte offsets. |
| Graphemes | External iterator for a string’sgrapheme clusters. |
| USentenceBoundIndices | External iterator for sentence boundaries and byte offsets. |
| USentenceBounds | External iterator for a string’ssentence boundaries. |
| UWordBoundIndices | External iterator for word boundaries and byte offsets. |
| UWordBounds | External iterator for a string’sword boundaries. |
| UnicodeSentences | An iterator over the substrings of a string which, after splitting the string onsentence boundaries,contain any characters with theAlphabeticproperty, or withGeneral_Category=Number. |
| UnicodeWordIndices | An iterator over the substrings of a string which, after splitting the string onword boundaries,contain any characters with theAlphabeticproperty, or withGeneral_Category=Number.This iterator also provides the byte offsets for each substring. |
| UnicodeWords | An iterator over the substrings of a string which, after splitting the string onword boundaries,contain any characters with theAlphabeticproperty, or withGeneral_Category=Number. |
| GraphemeIncomplete | An error return indicating that not enough content was available in theprovided chunk to satisfy the query, and that more content must be provided. |
| UNICODE_VERSION | The version ofUnicodethat this version of unicode-segmentation is based on. |
| UnicodeSegmentation | Methods for segmenting strings according toUnicode Standard Annex #29. |
