grapheme

This crate offers types related to extended Unicode grapheme clusters, which are replacements for the standard types char and str.

Features

• Replacement for the standard library char and str types.
• Optimized owning grapheme type.
• Macros g! and gs!, used as literals to create crate types, performing all necessary checks at compile time.

Usage

Add this to your Cargo.toml:

[dependencies]
grapheme = "1"

Then:

use grapheme::prelude::*;

let alpha = gs!("a 6 y̆ நி र्क");

let mut iter = alpha.iter().filter(|g| g.is_alphabetic());

assert_eq!(Some(g!("a")), iter.next());
assert_eq!(Some(g!("y̆")), iter.next());
assert_eq!(Some(g!("நி")), iter.next());
assert_eq!(Some(g!("र्क")), iter.next());

assert_eq!(None, iter.next());
