unic-langid

unic-langid is an API for managing Unicode Language Identifiers.

The crate provides a way to create a struct from a string, manipulate its fields, canonicalize it, and serialize into a string.

Usage

```rust use unic_langid::LanguageIdentifier;

let loc: LanguageIdentifier = "en-US".parse().expect("Parsing failed.");

asserteq!(loc.getlanguage(), "en"); asserteq!(loc.getscript(), None); asserteq!(loc.getregion(), Some("US"));

loc.set_script(Some("latn"));

asserteq!(&loc.tostring(), "en-Latn-US"); ```

```rust use unic_langid::LanguageIdentifier;

let langid = LanguageIdentifier::from_parts( Some("en"), None, None, Some(&["nedis", "macos"]) ).expect("Parsing failed.");

asserteq!(&langid.tostring(), "en-macos-nedis") ```

Macros

unic-langid can be also compiled with features = ["macros"] which enables langid! macro:

```rust use unic_langid::langid;

let lang = langid!("en-US");

asserteq!(&langid.tostring(), "en-US") ```

The macro allows for compile-time parsing and validation of literal language identifiers.

Status

The crate is providing fundamental blocks, but is very basic.

In particular, a lot can be done to improve performance and memory usage.
