Crate dobby_rs

This crate is a rusty binding of Dobby.

Quickstart

use dobby_rs::{resolve_symbol, hook, Address};
use std::mem::transmute;

#[inline(never)]
#[no_mangle]
extern "C" fn add(a: u64, b: u64) -> u64 {
    a + b
}

#[inline(never)]
#[no_mangle]
extern "C" fn sub(a: u64, b: u64) -> u64 {
    a - b
}

unsafe {
    let addr = add as usize as Address;
    let replace = sub as usize as Address;

    let origin = hook(addr, replace).unwrap();
    let origin: extern "C" fn(u64, u64) -> u64 = transmute(origin);

    assert_eq!(origin(2, 1), 2 + 1);
    assert_eq!(add(2, 1), 2 - 1);
}
