hyperlane 20.0.1

A lightweight, high-performance, and cross-platform Rust HTTP server library built on Tokio. It simplifies modern web service development by providing built-in support for middleware, WebSocket, Server-Sent Events (SSE), and raw TCP communication. With a unified and ergonomic API across Windows, Linux, and MacOS, it enables developers to build robust, scalable, and event-driven network applications with minimal overhead and maximum flexibility.
