Dark Factory — Rust → Zeta Autonomous Transpiler

Turn any Rust crate into a Zeta package. Automatically.

Dark Factory is the official Rust-to-Zeta transpiler, built by the Zeta Foundation. It parses Rust source code via syn, walks the AST, and emits equivalent Zeta source — preserving types, generics, traits, macros, extern blocks, and the full serde data model.

Used to produce all 46+ packages on zorbs.io, including:

• @async/tokio — Full async runtime, 373 files, 36k lines
• @stdlib/regex — Regular expression engine, 218 files, 69k lines
• @data/serde — Serialization framework, 24 files, 7.4k lines
• @net/hyper — HTTP/1.1 + HTTP/2 library
• @crypto/ring — Cryptography (AES, SHA, ECDSA, Ed25519)
• @net/hyper, @net/reqwest, @net/tower — Full web stack

Quick Start

# Convert a single Rust file
df convert input.rs -o output.zeta

# Convert an entire crate directory
df crate path/to/crate

# Fetch a crate from crates.io and convert it
df fetch serde

# Full pipeline: fetch → convert → compile → publish
df pipeline clap --publish

Installation

cargo install dark-factory

Commands

Command	Description
df convert <file>	Convert a single .rs file to Zeta
df crate <dir>	Convert an entire crate directory
df fetch <name>	Fetch a crate from crates.io and convert
df pipeline <name>	Full pipeline: fetch → convert → compile → publish
df rules	List available AST rewrite rules

How It Works

Dark Factory operates in three passes:

1. Parse — Uses syn to parse Rust source into a full AST (File, Items, Expressions, Types, Patterns, Macros)
2. Emit — Walks the AST and emits Zeta source text. Each Rust construct has a corresponding emit_* function:
   • emit_fn, emit_struct, emit_enum, emit_impl, emit_trait
   • emit_mod, emit_use, emit_const, emit_static, emit_type
   • emit_macro — full macro_rules! preservation
   • emit_foreign_mod — extern "C" block handling
3. Polish — An 11-phase post-processor cleans up proc_macro2 spacing artifacts (:: → ::, assert ! ( → assert!(, turbofish, generics, doc URLs, etc.)

Stats

Converted 46+ packages totaling ~300,000+ lines of Zeta with zero unsupported items across every crate. Tested on:

• serde (24 files, 7.4k lines)
• regex ecosystem (218 files, 69k lines)
• tokio (373 files, 36k lines)
• clap_builder (57 files, 11k lines)
• rayon + rayon-core (104 files, 17k lines)
• crossbeam ecosystem (42 files, 7.4k lines)
• futures ecosystem (409 files, 30k lines)
• And 35+ more
