Migrate to cargo_embargo. am: 99d47778c2 am: 6b4947a082 am: cabb9038e9 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/unicode-width/+/2828074 Change-Id: I3e25966bf76244824c0aaa4698735c2d4df1839c Signed-off-by: Automerger Merge Worker <[email protected]>
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"
