unicode-width

Determine displayed width of char and str types according to Unicode Standard Annex #11 rules.

Build Status

Documentation

extern crate unicode_width;

use unicode_width::UnicodeWidthStr;

fn main() {
    let teststr = "Hello, world!";
    let width = UnicodeWidthStr::width(teststr);
    println!("{}", teststr);
    println!("The above string is {} columns wide.", width);
    let width = teststr.width_cjk();
    println!("The above string is {} columns wide (CJK).", width);
}

NOTE: The computed width values may not match the actual rendered column width. For example, the woman scientist emoji comprises of a woman emoji, a zero-width joiner and a microscope emoji.

extern crate unicode_width;
use unicode_width::UnicodeWidthStr;

fn main() {
    assert_eq!(UnicodeWidthStr::width("👩"), 2); // Woman
    assert_eq!(UnicodeWidthStr::width("🔬"), 2); // Microscope
    assert_eq!(UnicodeWidthStr::width("👩‍🔬"), 4); // Woman scientist
}

See Unicode Standard Annex #11 for precise details on what is and isn't covered by this crate.
