A crate to read memory from another process. Code originally taken from Julia Evans' excellent ruby-stacktrace project.

Example

extern crate read_process_memory;

use std::io;
use read_process_memory::{Pid, TryIntoProcessHandle, CopyAddress, copy_address};

// Try to read `size` bytes at `address` from the process `pid`.
fn read_some_memory(pid: Pid, address: usize, size: usize) -> io::Result<()> {
    let handle = pid.try_into_process_handle()?;
    let _bytes = copy_address(address, size, &handle)?;
    println!("Read {} bytes", size);
    Ok(())
}

fn main() {
    read_some_memory(123 as Pid, 0x100000, 100).unwrap();
}
