Examples

Line Break

Segment a string with default options:

```rust use icu::segmenter::LineBreakSegmenter;

let segmenter = LineBreakSegmenter::trynewunstable(&icu_testdata::unstable()) .expect("Data exists");

let breakpoints: Vec = segmenter.segmentstr("Hello World").collect(); asserteq!(&breakpoints, &[6, 11]); ```

See [LineBreakSegmenter] for more examples.

Grapheme Cluster Break

See [GraphemeClusterBreakSegmenter] for examples.

Word Break

Segment a string:

```rust use icu::segmenter::WordBreakSegmenter;

let segmenter = WordBreakSegmenter::trynewunstable(&icu_testdata::unstable()) .expect("Data exists");

let breakpoints: Vec = segmenter.segmentstr("Hello World").collect(); asserteq!(&breakpoints, &[0, 5, 6, 11]); ```

See [WordBreakSegmenter] for more examples.
