rust-web-server 17.59.0

A dependency-minimal Rust web platform: HTTP/1.1, HTTP/2, and HTTP/3 server, reverse proxy, and application framework with routing, middleware (auth, rate limiting, tracing), an async ORM, background jobs, object storage, and a mailer. Runs as a zero-code config-driven proxy or as a library crate. No third-party HTTP dependencies.
