Name	Description	Size	Coverage
mod.rs	This module provides a data structure for a space-efficient and time-efficient lookup of sequences of 16-bit units (commonly but not necessarily UTF-16 code units) which map to integer values. It is an implementation of the existing [ICU4C UCharsTrie](https://unicode-org.github.io/icu-docs/apidoc/released/icu4c/classicu_1_1UCharsTrie.html) / [ICU4J CharsTrie](https://unicode-org.github.io/icu-docs/apidoc/released/icu4j/com/ibm/icu/util/CharsTrie.html) API. ## Architecture ICU4X [`Char16Trie`] is designed to provide a read-only view of `UCharsTrie` data that is exported from ICU4C. ## Examples ### Querying a `Char16Trie` ```rust use icu::collections::char16trie::{Char16Trie, TrieResult}; use zerovec::ZeroVec; // A Char16Trie containing the ASCII characters mapping 'a' to 1 and 'ab' // to 100. let trie_data = [48, 97, 176, 98, 32868]; let trie = Char16Trie::new(ZeroVec::from_slice_or_alloc(&trie_data)); let mut iter = trie.iter(); let res = iter.next('a'); assert_eq!(res, TrieResult::Intermediate(1)); let res = iter.next('b'); assert_eq!(res, TrieResult::FinalValue(100)); let res = iter.next('c'); assert_eq!(res, TrieResult::NoMatch); ``` [`ICU4X`]: ../icu/index.html	1621	-
