Snap for 7160059 from 9f27d8a3833581edc419d2f14b790e264ffa5ae3 to sc-release Change-Id: I25156ec567ff4235de4903acf1f235a06f1c92a2
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.
unicode-width does not depend on libstd, so it can be used in crates with the #![no_std]
attribute.
You can use this package in your project by adding the following to your Cargo.toml
:
[dependencies] unicode-width = "0.1.7"
