Zydis Rust Bindings

Rust bindings for Zydis, a fast and lightweight x86/x86-64 disassembler and code generator library.

[dependencies]
zydis = "4.1.1"

Example

use zydis::*;

#[rustfmt::skip]
static CODE: &'static [u8] = &[
    0x51, 0x8D, 0x45, 0xFF, 0x50, 0xFF, 0x75, 0x0C, 0xFF, 0x75, 0x08,
    0xFF, 0x15, 0xA0, 0xA5, 0x48, 0x76, 0x85, 0xC0, 0x0F, 0x88, 0xFC,
    0xDA, 0x02, 0x00,
];

fn main() -> zydis::Result {
    let fmt = Formatter::intel();
    let dec = Decoder::new64();

    // 0 is the address for our code.
    for insn_info in dec.decode_all::<VisibleOperands>(CODE, 0) {
        let (ip, _raw_bytes, insn) = insn_info?;
        
        // We use Some(ip) here since we want absolute addressing based on the given
        // instruction pointer. If we wanted relative addressing, we'd use `None` instead.
        println!("0x{:016X} {}", ip, fmt.format(Some(ip), &insn)?);
    }

    Ok(())
}

Version Map

Since version 3.0.0 the binding's major and minor versions are tethered to the Zydis version. The binding's patch version is independent of the Zydis version and can be bumped for binding-only changes. Every cargo crate release has a corresponding git tag.
