Expand description

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

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);

    println!("The above string is {} columns wide (CJK).", width);


unicode-width supports a no_std feature. This eliminates dependence on std, and instead uses equivalent functions from core.


You can use this package in your project by adding the following to your Cargo.toml:

unicode-width = "0.1.5"
