## What it is
Enigma is an implementation of the Erlang VM (BEAM) written in Rust, aiming to run OTP 22+ and Elixir code unchanged. It is a learning-oriented reimplementation covering most opcodes and about half of the BIFs, with the Erlang shell and IEx able to boot.

## Use cases
- run erlang code on an alternative vm
- learn how the beam vm works internally
- experiment with erlang vm implementation ideas in rust
- boot an erlang shell without installing erlang
- study interpreter and process scheduling design

## When to choose
- you want to study or hack on a small, readable BEAM implementation
- you're prototyping VM ideas for potential inclusion in BEAM
- you're learning Erlang/Elixir internals

## When to avoid
- you need a production Erlang/Elixir runtime
- you need distributed Erlang, NIFs, ports, timers, or full file IO
- you need stability - the project expects crashes and is no longer actively maintained

## Facets
- artifact type: library
- maturity: abandoned
- function: interpreter, concurrency, programming-language
- domain: programming-languages, compilers, developer-tools
- platform: windows, rust
- tags: erlang-vm, beam, elixir, virtual-machine, otp, runtime, linux, macos
