libgoblin

Goblin requires rustc 1.85.0 (Rust 2024 edition).

Add to your Cargo.toml

[dependencies]
goblin = "0.10"

awesome crate name
zero-copy, cross-platform, endian-aware, ELF64/32 implementation - wow!
zero-copy, cross-platform, endian-aware, 32/64 bit Mach-o parser - zoiks!
PE 32/64-bit parser - bing!
a Unix and BSD style archive parser (latter courtesy of @willglynn) - huzzah!
many cfg options - it will make your head spin, and make you angry when reading the source!
fuzzed - "I am happy to report that goblin withstood 100 million fuzzing runs, 1 million runs each for seed 1~100." - @sanxiyn
tests

libgoblin aims to be your one-stop shop for binary parsing, loading, and analysis.

Goblin primarily supports the following important use cases:

Core, std-free #[repr(C)] structs, tiny compile time, 32/64 (or both) at your leisure.
Type punning. Define a function once on a type, but have it work on 32 or 64-bit variants - without really changing anything, and no macros! See examples/automagic.rs for a basic example.
std mode. This throws in read and write impls via Pread and Pwrite, reading from file, convenience allocations, extra methods, etc. This is for clients who can allocate and want to read binaries off disk.
Endian_fd. A truly terrible name 😆 this is for binary analysis like in panopticon or falcon which needs to read binaries of foreign endianness, or as a basis for constructing cross platform foreign architecture binutils, e.g. cargo-sym and bingrep are simple examples of this, but the sky is the limit.

Here are some things you could do with this crate (or help to implement so they could be done):

Write a compiler and use it to generate binaries (all the raw C structs have Pwrite derived).
Write a binary analysis tool which loads, parses, and analyzes various binary formats, e.g., panopticon or falcon.
Write a semi-functioning dynamic linker.
Write a kernel and load binaries using no_std cfg. I.e., it is essentially just struct and const defs (like a C header) - no fd, no output, no std.
Write a bin2json tool, because why shouldn't binary formats be in JSON?

libgoblin is designed to be massively configurable. The current flags are:
