rhai-memflow = "0.1"
# `rhai-memflow` uses version `^0.2.0-beta`, this .
memflow = { version = "^0.2.0-beta", features = ["plugins"] }

Rhai script

let calc_proc = OS.process("CalculatorApp.exe");
let mod_base = calc_proc.mod("CalculatorApp.dll").base;

// Our native!
native COFFHeader {
    ^ 6, // Pad 6 bytes.
    sections: UInt16,
    timestamp: UInt32
};

let coff_header = calc_proc.read(COFFHeader, mod_base + 0x40);
print(coff_header);

Rust source

use memflow::prelude::v1::*;
use rhai::{packages::Package, Engine, Scope};

// Create our inventory and OS.
let inventory = Inventory::scan();
let os = inventory.builder().os_chain(chain).build()?;

// Register our memflow package.
let mut engine = Engine::new();
let package = MemflowPackage::new();
package.register_into_engine(&mut engine);

// Add our OS to rhai scope.
let mut scope = Scope::new();
let shared_os: SharedOs = RefCell::new(os);
scope.push_constant("OS", shared_os);

// Run our script.
engine
    .eval_with_scope::<()>(&mut scope, include_str!("script.rhai"))
    .expect("eval failed");
