Simple way to edit memory with rust

Simple base I use to get a handle to a process and write to its memory. It can also get what keys are being pressed.

Written all in rust.

Example

main.rs thats read and writes to some pointers in memory of SomeDllOrExe

#[path = "mem_util/input.rs"]
mod input;

#[path = "mem_util/memory.rs"]
mod memory;

fn main() {
    /*for i in 1..100 {
        input::setCursorPos(i, 2*i);
    }*/

    let process = memory::attach("SomeExecutable.exe");
    let module = memory::Module::get_module("SomeExecutable.exe", "SomeDllOrExe.dll");

    //Evaluate multi level pointer for a 32 bit app
    let some_base_ptr =
        process.pointer_from_offsets32(vec![module.m_dw_base + 0xDEADBEEF, 0xF0, 0x0, 0xCC]);

    let offset_from_base_ptr = some_base_ptr + 0x8; //8 bytes ahead of first the multi level pointer

    let _read_value_float = process.read_memory::<f32>(offset_from_base_ptr); //Reads value of memory as a float
    let _read_value_unsigned_int = process.read_memory::<u32>(offset_from_base_ptr); //Reads value of memory as unsigned 32 bit integer

    //Write some NOP instructions to memory, or any other byte sequence
    process.write_memory::<[u8; 4]>(module.m_dw_base + 0x13370, [0x90, 0x90, 0x90, 0x90]);
    //Is A key pressed?
    //https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes
    if input::pressed(0x41) {
        process.write_memory::<f32>(offset_from_base_ptr, 123.0) //Writes 123.0 as float to memory location,
    }
}
