Phasm

Phasm is a fast and flexible assembler written in Rust. It aims to support encoding and decoding assembly instructions for x86 and ARM, with ELF integration.

Goals

• Encoding & Decoding: Convert assembly code to machine code and vice versa.
• Multi-Architecture Support: Supports x86 and ARM architectures.
• ELF Integration: Work with ELF binaries.
• Modular Design: Enable only the features you need.

Installation

Add phasm as a dependency in your Cargo.toml:

[dependencies]
phasm = "0.1"

To use specific features:

[dependencies]
phasm = { version = "0.1", features = ["x86", "encode"] }

Usage

Encoding an Instruction

use phasm::arm::ArmAssembler;

let machine_code = ArmAssembler::encode("mov r0, r1").unwrap();
println!("{:x?}", machine_code);

Decoding an Instruction

use phasm::x86::X86Assembler;

let assembly = X86Assembler::decode(&[0x89, 0xD8]).unwrap();
println!("{:?}", assembly);
