Crates

This project is made up of three crates.

ctor

Module initialization functions for Rust (like __attribute__((constructor)) in C/C++).

Run code before main to initialize data, external resources, or other state.

use ctor::ctor;

#[ctor(unsafe)]
fn foo() {
    println!("Life before main!");
}

dtor

Module shutdown functions for Rust (like __attribute__((destructor))).

Run code after main to clean up resources, or perform other final operations.

use dtor::dtor;

#[dtor(unsafe)]
fn foo() {
    println!("Life after main!");
}

link-section

Typed and untyped link section support for Rust.

Collect related items from an entire linked binary into a single link section.

use link_section::{section, in_section, TypedSection};
use ctor::ctor;

#[section]
static FOO: TypedSection<u32>;

#[in_section(FOO)]
fn foo() {
    println!("Hello, world!");
}

#[ctor(unsafe)]
fn print_numbers() {
    for i in *FOO {
        println!("{}", i);        
    }
}
