Function graphemes

Source 
pub fn graphemes(s: &str) -> Vec<&str>
Expand description

Returns all Unicode grapheme clusters in the input string, following UAX #29.

A grapheme cluster is the smallest unit of text that a user perceives as a single character. This function implements Unicode® Standard Annex #29, including support for extended grapheme clusters such as:

  • Emoji ZWJ sequences (e.g., 👩‍❤️‍💋‍👨)
  • Hangul syllables
  • Combining accents (e.g., é)

This API is Unicode-compliant and suitable for user-facing string segmentation.

§Arguments

  • s – The input string to split.

§Returns

A Vec<&str> where each item is a Unicode grapheme cluster.

§Example

use runefix_core::graphemes;

let clusters = graphemes("Love👩‍❤️‍💋‍👨爱");
assert_eq!(clusters, vec!["L", "o", "v", "e", "👩‍❤️‍💋‍👨", "爱"]);
