Macro tr::set_translator

macro_rules! set_translator {
    ($translator:expr) => { ... };
}

Set the translator to be used for this crate.

The argument needs to be something implementing the Translator trait

For example, using the gettext crate (if the gettext feature is enabled)

let f = File::open("french.mo").expect("could not open the catalog");
let catalog = Catalog::parse(f).expect("could not parse the catalog");
set_translator!(catalog);
