Macro gettextrs::ngettext

macro_rules! ngettext {
    ($msgid:expr, $msgid_plural:expr, $n:expr, $($args:expr),+ $(,)?) => { ... };
}

Like ngettext, but allows for formatting.

It calls ngettext on msgid, msgid_plural, and n, and then replaces each occurrence of {} with the next value out of args.
