Crate icu_casemap

Case mapping for Unicode characters and strings.

This module is published as its own crate (icu_casemap) and as part of the icu crate. See the latter for more details on the ICU4X project.

Examples

use icu::casemap::CaseMapper;
use icu::locid::langid;

let cm = CaseMapper::new();

assert_eq!(
    cm.uppercase_to_string("hello world", &langid!("und")),
    "HELLO WORLD"
);
assert_eq!(
    cm.lowercase_to_string("Γειά σου Κόσμε", &langid!("und")),
    "γειά σου κόσμε"
);

Structs

• CaseMapCloser
  A wrapper around CaseMapper that can produce case mapping closures over a character or string. This wrapper can be constructed directly, or by wrapping a reference to an existing CaseMapper.
• CaseMapper
  A struct with the ability to convert characters and strings to uppercase or lowercase, or fold them to a normalized form for case-insensitive comparison.

Traits

• ClosureSink
  An object that accepts characters and/or strings to be used with CaseMapCloser::add_string_case_closure_to() and CaseMapCloser::add_case_closure_to(). Usually this object will be some kind of set over codepoints and strings, or something that can be built into one.
