[−][src]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. c
Macros

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. |
