Module icu_collections::codepointtrie

source ·
Expand description

This module provides a data structure for an time-efficient lookup of values associated to code points.

It is an implementation of the existing ICU4C UCPTrie / ICU4J CodePointTrie API.

§Architecture

ICU4X CodePointTrie is designed to provide a read-only view of CodePointTrie data that is exported from ICU4C. Detailed information about the design of the data structure can be found in the documentation for the CodePointTrie struct.

§Examples

§Querying a CodePointTrie

use icu::collections::codepointtrie::planes;
let trie = planes::get_planes_trie();

assert_eq!(0, trie.get32(0x41)); // 'A' as u32
assert_eq!(0, trie.get32(0x13E0)); // 'Ꮰ' as u32
assert_eq!(1, trie.get32(0x10044)); // '𐁄' as u32

Traits§

  • A trait representing the values stored in the data array of a CodePointTrie. This trait is used as a type parameter in constructing a CodePointTrie.
