//! This module is published as its own crate ([`icu_properties`](https://docs.rs/icu_properties/latest/icu_properties/))

//!
//! APIs that return a [`CodePointSetData`] exist for binary properties and certain enumerated
//! properties. See the [`sets`] module for more details.
//!
//! APIs that return a [`CodePointMapData`] exist for certain enumerated properties. See the

//! # Examples
//!
//! ## Property data as `CodePointSetData`s
//!
//! ```
//! use icu::properties::{maps, sets, GeneralCategory};
//!
//! // A binary property as a `CodePointSetData`
//!
//! assert!(sets::emoji().contains('��')); // U+1F383 JACK-O-LANTERN
//! assert!(!sets::emoji().contains('木')); // U+6728
//!
//! // An individual enumerated property value as a `CodePointSetData`
//!
//! let line_sep_data = maps::general_category()
//!     .get_set_for_value(GeneralCategory::LineSeparator);
//! let line_sep = line_sep_data.as_borrowed();
//!
//! assert!(line_sep.contains32(0x2028));
//! assert!(!line_sep.contains32(0x2029));
//! ```
//!
//! ## Property data as `CodePointMapData`s
//!
//! ```
//! use icu::properties::{maps, Script};
//!
//! assert_eq!(maps::script().get('��'), Script::Common); // U+1F383 JACK-O-LANTERN
//! assert_eq!(maps::script().get('木'), Script::Han); // U+6728
