[][src]Crate contructor_derive

Registers a function to be called before/after main (if an executable) or when loaded/unloaded (if a dynamic library).

Notes

Use this library is unsafe unless you want to interop directly with a FFI library.

Please consider to use the lazy-static crate instead of it.

Usage

Add the following dependency to your Cargo manifest...

[dependencies]
contructor_derive = "0.1.0"

Example

#[macro_use]
extern crate contructor_derive;

pub static mut RAN: bool = false;

#[constructor]
extern "C" fn set_ran() {
    unsafe { RAN = true }
}

#[destructor]
extern "C" fn reset_ran() {
    unsafe { RAN = false }
}

fn main() {
    assert!(unsafe { RAN });
}
