uax14_rs

A line breaker that is compatible with Unicode Standard Annex #14 and CSS properties.

use uax14_rs::LineBreakIterator;

fn main () {
    let mut iter = LineBreakIterator::new("Hello World");
    let result: Vec<usize> = iter.collect();
    println!("{:?}", result);
}

With CSS property.

use uax14_rs::{LineBreakIterator, LineBreakRule, WordBreakRule};

fn main() {
    let iter = LineBreakIterator::new_with_break_rule(
        "Hello World",
        LineBreakRule::Strict,
        WordBreakRule::BreakAll,
        false,
    );
    let result: Vec<usize> = iter.collect();
    println!("{:?}", result);
}

Use Latin 1 string for C binding and etc.

use uax14_rs::LineBreakIteratorLatin1;

fn main () {
    let s = "Hello World";
    let iter = LineBreakIteratorLatin1::new(s.as_bytes());
    let result: Vec<usize> = iter.collect();
    println!("{:?}", result);
}
