Previously the user data of MMIO callbacks would live until the end of the containing Unicorn engine. Now they are deallocated once all memory referencing those callbacks has been unmapped.
Unicorn-engine
Rust bindings for the Unicorn emulator with utility functions.
Checkout Unicorn2 source code at dev branch.
use unicorn_engine::{Unicorn, RegisterARM};
use unicorn_engine::unicorn_const::{Arch, Mode, Permission, SECOND_SCALE};
fn main() {
let arm_code32: Vec<u8> = vec![0x17, 0x00, 0x40, 0xe2]; // sub r0, #23
let mut unicorn = Unicorn::new(Arch::ARM, Mode::LITTLE_ENDIAN).expect("failed to initialize Unicorn instance");
let mut emu = unicorn.borrow();
emu.mem_map(0x1000, 0x4000, Permission::ALL).expect("failed to map code page");
emu.mem_write(0x1000, &arm_code32).expect("failed to write instructions");
emu.reg_write(RegisterARM::R0, 123).expect("failed write R0");
emu.reg_write(RegisterARM::R5, 1337).expect("failed write R5");
let _ = emu.emu_start(0x1000, (0x1000 + arm_code32.len()) as u64, 10 * SECOND_SCALE, 1000);
assert_eq!(emu.reg_read(RegisterARM::R0, Ok(100));
assert_eq!(emu.reg_read(RegisterARM::R5, Ok(1337));
}
Further sample code can be found in tests/unicorn.rs.

These bindings are based on Sébastien Duquette's (@ekse) unicorn-rs. We picked up the project, as it is no longer maintained. Thanks to all contributors.
