Crate label

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.

Macros

create_label

Creates a new label.

Attribute Macros

ctor	Marks a function or static variable as a library/executable constructor. This uses OS-specific linker sections to call a specific function at load time.
