unicode-width
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);
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.
