Macro icu::locid::macros::variant

variant!() { /* proc-macro */ }

A macro allowing for compile-time construction of valid Variant subtag.

The macro will perform syntax canonicalization of the tag.

Examples

use icu::locid::subtags::Variant;
use icu::locid::macros::variant;

const POSIX: Variant = variant!("Posix");

let posix: Variant = "Posix".parse()
    .expect("Failed to parse variant subtag.");

assert_eq!(POSIX, "posix");
assert_eq!(POSIX, posix);
