Expand description

Unicode character composition and decomposition utilities as described in Unicode Standard Annex #15.

extern crate unicode_normalization;

use unicode_normalization::char::compose;
use unicode_normalization::UnicodeNormalization;

fn main() {
    assert_eq!(compose('A','\u{30a}'), Some('Å'));

    let s = "ÅΩ";

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

[dependencies]
unicode-normalization = "0.1.20"

Modules§

  • Methods for composing and decomposing characters.

Structs§

  • External iterator for a string decomposition’s characters.
  • External iterator for a string recomposition’s characters.
  • External iterator for replacements for a string’s characters.
  • UAX15-D4: This iterator keeps track of how many non-starters there have been since the last starter in NFKD and will emit a Combining Grapheme Joiner (U+034F) if the count exceeds 30.

Enums§

  • QuickCheck quickly determines if a string is normalized, it can return Maybe

Constants§

Traits§

Functions§

  • Authoritatively check if a string is in NFC.
  • Quickly check if a string is in NFC, potentially returning IsNormalized::Maybe if further checks are necessary. In this case a check like s.chars().nfc().eq(s.chars()) should suffice.
  • Authoritatively check if a string is Stream-Safe NFC.
  • Quickly check if a string is Stream-Safe NFC.
  • Authoritatively check if a string is in NFD.
  • Quickly check if a string is in NFD.
  • Authoritatively check if a string is Stream-Safe NFD.
  • Quickly check if a string is Stream-Safe NFD.
  • Authoritatively check if a string is in NFKC.
  • Quickly check if a string is in NFKC.
  • Authoritatively check if a string is in NFKD.
  • Quickly check if a string is in NFKD.
