5//! This module provides a data structure for an time-efficient lookup of values
6//! associated to code points.
7//!
8//! It is an implementation of the existing [ICU4C UCPTrie](https://unicode-org.github.io/icu-docs/apidoc/released/icu4c/ucptrie_8h.html)
9//! / [ICU4J CodePointTrie](https://unicode-org.github.io/icu-docs/apidoc/dev/icu4j/) API.
10//!
11//! # Architecture
12//!
13//! ICU4X [`CodePointTrie`] is designed to provide a read-only view of [`CodePointTrie`] data that is exported
14//! from ICU4C. Detailed information about the design of the data structure can be found in the documentation
15//! for the [`CodePointTrie`] struct.
16//!
17//! # Examples
18//!
19//! ## Querying a `CodePointTrie`
20//!
21//! ```
22//! use icu::collections::codepointtrie::planes;
23//! let trie = planes::get_planes_trie();
24//!
25//! assert_eq!(0, trie.get32(0x41)); // 'A' as u32
26//! assert_eq!(0, trie.get32(0x13E0)); // 'Ꮰ' as u32
27//! assert_eq!(1, trie.get32(0x10044)); // '𐁄' as u32
28//! ```
