+
+//! Efficient collections for Unicode data.
+//!
+//! This module is published as its own crate ([`icu_collections`](https://docs.rs/icu_collections/latest/icu_collections/))
+//! and as part of the [`icu`](https://docs.rs/icu/latest/icu/) crate. See the latter for more details on the ICU4X project.
+//!
+//! ICU4X [`CodePointTrie`](crate::codepointtrie::CodePointTrie) provides 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`](crate::codepointtrie::CodePointTrie) struct.
+//!
+//! ICU4X [`CodePointInversionList`](`crate::codepointinvlist::CodePointInversionList`) provides necessary functionality for highly efficient querying of sets of Unicode characters.
+//! It is an implementation of the existing [ICU4C UnicodeSet API](https://unicode-org.github.io/icu-docs/apidoc/released/icu4c/classicu_1_1UnicodeSet.html).
+//!
+//! ICU4X [`Char16Trie`](`crate::char16trie::Char16Trie`) 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.
