System Documentation

What problem does it solve?

Alef eliminates the repetitive, error-prone work of manually writing and keeping multi-language bindings in sync with a Rust codebase, so your generated APIs stay accurate as your Rust sources evolve.

Core Features & Use Cases

  • One config, many languages: Generate fully-typed language bindings from a single Rust-focused source-of-truth configuration for 16 backends (e.g., Python, Node/TypeScript, WASM, Ruby, PHP, Go, Java, C#, Kotlin, Elixir, Gleam, R, Swift, Dart, Zig, C).
  • End-to-end pipeline: Extract API surface, generate bindings and type stubs, scaffold packages, generate per-language READMEs/docs, and optionally create fixture-driven e2e test suites.
  • CI-friendly freshness guarantees: Use verify/diff to detect stale generated outputs via embedded per-file hashes, preventing silently diverging bindings across languages.
  • Advanced interoperability patterns: Configure DTO styles, trait bridges, adapter patterns, FFI layers, version syncing, and pre-commit hooks to fit real-world library publishing workflows.

Quick Start

Run alef generate to produce the configured language bindings from your Rust crate and alef.toml configuration.
