eetf

What problem does it solve?

The eetf skill solves the problem of converting Erlang External Term Format (ETF) binaries into usable Rust values and encoding Rust data back into ETF bytes for BEAM interop.

Core Features & Use Cases

• Decode ETF terms from bytes: Parse ETF payloads that begin with the version byte 131 (0x83) into strongly-typed Rust representations.
• Encode Rust terms to ETF bytes: Produce payloads compatible with Erlang/Elixir producers like term_to_binary/1 and consumers like binary_to_term/1.
• Handle BEAM-specific types and patterns: Support atoms, binaries, lists (including ByteList/STRING_EXT), tuples, maps, pids/ports/references, and provide pattern matching helpers for {ok, Value}/ {error, Reason}-style replies.

Quick Start

Use eetf to decode the attached ETF bytes into a Rust Term value, then encode that Term back into ETF bytes.
