Macro tkv 

macro_rules! tkv {
    ($msg:literal) => { ... };
}

It’s useful when you want to use a long string as a key, but you don’t want to type it twice.

Arguments

Returns

A tuple of (key, msg).

Example

use rust_i18n::{t, tkv};


let (key, msg) = tkv!("Hello world");
// => key is `"Hello world"` and msg is the translated message.
// => If there is hints the minify_key logic, the key will returns a minify key.
