Macro kailua_diag::define_msg

macro_rules! define_msg {
    ($(#[$meta:meta])* pub $name:ident $($t:tt)*) => { ... };
    ($(#[$meta:meta])* $name:ident $($t:tt)*) => { ... };
}

A helper macro for defining a localizable message.

define_msg! { pub StructName { param: OtherLocalizableType }:
    "lang1" => "Some localized string with a parameter {param}",
    "lang2" => "Some other localized string with a differently formatted parameter {param:10}",
    _       => "The default string with a parameter {param}, normally in English",
}

Each parameter should be localizable. pub and the parameters can be omitted, and type or lifetime parameters can be given. (But note that the constructor itself is a struct, so StructName {} is required even when there are no message parameters.)

Dependencies

This macro internally depends a parse_generics_shim crate, so any crate using this macro should put the following to the Cargo.toml...

[dependencies]
parse-generics-shim = "*"

...and the following to the crate root.

#[macro_use] extern crate parse_generics_shim;
