Crate icu_uniset[−][src]

icu_uniset is one of the ICU4X components.

This API provides necessary functionality for highly efficient querying of sets of Unicode characters.

It is an implementation of the existing ICU4C UnicodeSet API.

Architecture

ICU4X UnicodeSet is split up into independent levels, with UnicodeSet representing the membership/query API, and UnicodeSetBuilder representing the builder API. A Properties API is in future works.

Examples:

Creating a `UnicodeSet`

UnicodeSets are created from either serialized UnicodeSets, represented by inversion lists, the UnicodeSetBuilder, or from the TBA Properties API.

use icu::uniset::{UnicodeSet, UnicodeSetBuilder};

let mut builder = UnicodeSetBuilder::new();
builder.add_range(&('A'..'Z'));
let set: UnicodeSet = builder.build();

assert!(set.contains('A'));

Querying a `UnicodeSet`

Currently, you can check if a character/range of characters exists in the UnicodeSet, or iterate through the characters.

use icu::uniset::{UnicodeSet, UnicodeSetBuilder};

let mut builder = UnicodeSetBuilder::new();
builder.add_range(&('A'..'Z'));
let set: UnicodeSet = builder.build();

assert!(set.contains('A'));
assert!(set.contains_range(&('A'..='C')));
assert_eq!(set.iter_chars().next(), Some('A'));

Modules
