Function that takes no arguments

[synthe102]

Hi !

I'd like to implement a function that takes no arguments.
However, Lua.create_function() expects the rust function to take two arguments.
How can I solve this ?

Thanks !

let func = lua.create_function(|_, ()| Ok("hello")).unwrap();

Closely related, but the other way around I have a question at #266 about how to call a function without passing any args.
