 **[API Documentation](https://docs.rs/capstone/)**

Bindings to the [capstone library][upstream] disassembly framework.

The `Capstone` struct is the main interface to the library.

# Requirements

`capstone-rs` uses the [`capstone-sys`](capstone-sys) crate to provide the low-level bindings to the Capstone C library.

See the [`capstone-sys`](capstone-sys) page for the requirements and supported platforms.

* Minimum Rust Version: `1.70.0`

# Example

```rust

extern crate capstone;

use capstone::prelude::*;

const X86_CODE: &'static [u8] = b"\x55\x48\x8b\x05\xb8\x13\x00\x00\xe9\x14\x9e\x08\x00\x45\x31\xe4";

/// Print register names

fn reg_names(cs: &Capstone, regs: &[RegId]) -> String {

    let names: Vec = regs.iter().map(|&x| cs.reg_name(x).unwrap()).collect();

    names.join(", ")

}

/// Print instruction group names

fn group_names(cs: &Capstone, regs: &[InsnGroupId]) -> String {

    let names: Vec = regs.iter().map(|&x| cs.group_name(x).unwrap()).collect();

    names.join(", ")

}

fn main() {

    let cs = Capstone::new()

        .x86()

        .mode(arch::x86::ArchMode::Mode64)

        .syntax(arch::x86::ArchSyntax::Att)

        .detail(true)

        .build()

        .expect("Failed to create Capstone object");

    let insns = cs.disasm_all(X86_CODE, 0x1000)

        .expect("Failed to disassemble");

    println!("Found {} instructions", insns.len());

    for i in insns.as_ref() {

        println!();

        println!("{}", i);

        let detail: InsnDetail = cs.insn_detail(&i).expect("Failed to get insn detail");

        let arch_detail: ArchDetail = detail.arch_detail();

        let ops = arch_detail.operands();

        let output: &[(&str, String)] = &[

            ("insn id:", format!("{:?}", i.id().0)),

            ("bytes:", format!("{:?}", i.bytes())),

            ("read regs:", reg_names(&cs, detail.regs_read())),

            ("write regs:", reg_names(&cs, detail.regs_write())),

            ("insn groups:", group_names(&cs, detail.groups())),

        ];

        for &(ref name, ref message) in output.iter() {

            println!("{:4}{:12} {}", "", name, message);

        }

        println!("{:4}operands: {}", "", ops.len());

        for op in ops {

            println!("{:8}{:?}", "", op);

        }

    }

}

```

Produces:

```plain

Found 4 instructions

0x1000: pushq %rbp

    read regs:   rsp

    write regs:  rsp

    insn groups: mode64

0x1001: movq 0x13b8(%rip), %rax

    read regs:

    write regs:

    insn groups:

0x1008: jmp 0x8ae21

    read regs:

    write regs:

    insn groups: jump

0x100d: xorl %r12d, %r12d

    read regs:

    write regs:  rflags

    insn groups:

```

# Features

- `full`†: do not compile Capstone C library in

  [diet mode](https://www.capstone-engine.org/diet.html)

- `std`†: enable `std`-only features, such as the

  [`Error` trait](https://doc.rust-lang.org/std/error/trait.Error.html)

- `use_bindgen`: run `bindgen` to generate Rust bindings to Capstone C library

  instead of using pre-generated bindings (not recommended).

†: enabled by default
