Receive callback

[alanhoff]

Hello there, I would like to know how one could receive a callback from a Lua's return value.

fn main() {
    let mut lua = hlua::Lua::new();

    lua.execute::<()>(r#"
      function callback()
        return function (a, b)
          return a + b
        end
      end
    "#).unwrap();

    let mut cb: hlua::LuaFunction<_> = lua.get("callback").unwrap();
    let value: hlua::AnyLuaValue = cb.call().unwrap();
    println!("{:?}", value);
}

The code above returns a LuaOther type unfortunately.

You should be able to do this:

let value: hlua::LuaFunction<_> = cb.call().unwrap();

If you need a AnyLuaValue then it's unfortunately not implemented yet.
