Label

label is a library that can be used to create custom attributes for functions, through which you can list them and perform actions on them.

Example

use label::create_label;

create_label!(fn test() -> (););

#[test::label]
fn my_fn()  {
println!("Test!");
}

fn main() {
println!("calling all 'test' label");
// using iter you can go through all functions with this annotation.
for i in test::iter() {
i();
}
}

Guarantees

It is not supported to rely on the on the ordering of test::iter() in any situation. However, it is guaranteed that once the order is set at the start of the application, it stays that way until the application is stopped.
