"Shipping Rust to Python, Typescript, and Ruby Users"
summary
Core logic (compiler, diagnostics, runtime) lives in Rust and exposes language bindings to Python, TypeScript, Ruby, and Go using pyo3 N‑API Magnus libc. A six‑person team writes ~150,000 lines of Rust over ~18 months, producing thin FFI shims, cross‑compiles across 4 targets × 6 architectures (≈24 builds), and uses cargo / build.rs for CI. Design choices include using Python‑native objects when ergonomics matter, adopting synchronous versioning for all packages, and a callback‑driven stream pattern (Tokio + Python async generator) that works reliably.
