hello everybody,
I'm new here and in Rust, and I'm trying to write a little game in Rust.
In my situation, I got a lot of initializing functions to call, like:
- room manager: init_room_mgr,
- player manager: init_player_mgr,
- and etc.
as there are too many things like these in games, and they varies a lot, it is not rational to always insert new lines into my bootstrap code like main.rs.
so I've been expecting something like a macro, to mark those init funcs and then call them at once, like:
// in mod1.rs
#something_I_wanted(stage1)
pub fn init_fn1(){
....
}
// in mod2.rs
#something_I_wanted(stage1)
pub fn init_fn2(){
....
}
// in mod3.rs
#something_I_wanted(stage2)
pub fn init_fn3(){
....
}
// in main.rs
pub fn main(){
something_to_call_functions_for(stage1);
something_to_call_functions_for(stage2);
}
But I don't know how to code that thing exactly, even after I read the macro section in the book.
so, if there is something I can use from crates.io, or any one can give me a simple example for such a macro?
thanks!
