README.md

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

use unicode_segmentation::UnicodeSegmentation;

fn main() {
    let s = "a̐éö̲\r\n";
    let g = s.graphemes(true).collect::<Vec<&str>>();
    let b: &[_] = &["a̐", "é", "ö̲", "\r\n"];
    assert_eq!(g, b);

    let s = "The quick (\"brown\") fox can't jump 32.3 feet, right?";
    let w = s.unicode_words().collect::<Vec<&str>>();
    let b: &[_] = &["The", "quick", "brown", "fox", "can't", "jump", "32.3", "feet", "right"];
    assert_eq!(w, b);

    let s = "The quick (\"brown\")  fox";
    let w = s.split_word_bounds().collect::<Vec<&str>>();
    let b: &[_] = &["The", " ", "quick", " ", "(", "\"", "brown", "\"", ")", " ", " ", "fox"];
    assert_eq!(w, b);
}
