The author ported the OpenAI Python SDK to Rust in 5 days using Claude Code, resulting in 'openai-oxide' — a Rust client covering 100+ API methods. Key features include persistent WebSocket sessions for agentic loops (40% faster than HTTP REST), derive-macro-based structured outputs eliminating manual JSON schema construction, and zero-copy SSE streaming with WASM deployment support for Cloudflare Workers.
