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...

toml [dependencies] contructor_derive = "0.1.0"

Example

```rust

[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 }); } ```
