Efficient collections for Unicode data. 6 //! 7 //! This module is published as its own crate ([`icu_collections`](https://docs.rs/icu_collections/latest/icu_collections/)) 8 //! and as part of the [`icu`](https://docs.rs/icu/latest/icu/) crate. See the latter for more details on the ICU4X project. 9 //! 10 //! ICU4X [`CodePointTrie`](crate::codepointtrie::CodePointTrie) provides a read-only view of `CodePointTrie` data that is exported 11 //! from ICU4C. Detailed information about the design of the data structure can be found in the documentation 12 //! for the [`CodePointTrie`](crate::codepointtrie::CodePointTrie) struct. 13 //! 14 //! ICU4X [`CodePointInversionList`](`crate::codepointinvlist::CodePointInversionList`) provides necessary functionality for highly efficient querying of sets of Unicode characters. 15 //! It is an implementation of the existing [ICU4C UnicodeSet API](https://unicode-org.github.io/icu-docs/apidoc/released/icu4c/classicu_1_1UnicodeSet.html). 16 //! 17 //! ICU4X [`Char16Trie`](`crate::char16trie::Char16Trie`) provides a data structure for a space-efficient and time-efficient lookup of 18 //! sequences of 16-bit units (commonly but not necessarily UTF-16 code units) 19 //! which map to integer values. 20 //!
