## What it is
Goblin is a Rust library for parsing and loading binary executable formats including ELF, Mach-O, PE, and Unix/BSD archives. It offers zero-copy, endian-aware, 32/64-bit parsing with optional no_std support for kernels and binary analysis tools.

## Use cases
- parse ELF binaries in Rust
- read Mach-O executables
- inspect PE32/PE64 files
- build a binary analysis tool
- write a dynamic linker
- emit object files from a compiler
- analyze binaries of foreign endianness
- run in a no_std kernel to load executables

## When to choose
- you need a mature, heavily fuzzed Rust parser for ELF/Mach-O/PE formats
- you need zero-copy or no_std parsing for kernels or embedded analysis
- you want one crate handling multiple executable formats with 32/64-bit support

## When to avoid
- you need to execute or emulate binaries rather than parse them
- you need formats beyond ELF/Mach-O/PE/archive (e.g., DWARF debug info is separate)
- you are not working in Rust

## Facets
- artifact type: library
- maturity: stable
- function: parser, reverse-engineering, developer-tools
- domain: parsers, reverse-engineering, developer-tools, security
- platform: rust, cross-platform, cli
- tags: elf, mach-o, pe, binary-analysis, zero-copy, no-std, executable-formats, archive
