extern crate unicode_segmentation;

use unicode_segmentation::UnicodeSegmentation;

fn main() { let s = "a̐éö̲\r\n"; let g = UnicodeSegmentation::graphemes(s, 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"];
