+# unicorn-rs
+
+Rust bindings for the [Unicorn](http://www.unicorn-engine.org/) emulator with utility functions.
+
+An extended version for fuzzing with AFL++ support can be found in https://github.com/aflplusplus/unicornafl.
+
+```rust
+use unicorn::RegisterARM;
+use unicorn::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::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 as i32, 123).expect("failed write R0");
+    emu.reg_write(RegisterARM::R5 as i32, 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 as i32), Ok(100));
+    assert_eq!(emu.reg_read(RegisterARM::R5 as i32), Ok(1337));
+}
+```
+Further sample code can be found in ```tests/unicorn.rs```.
