• Event loop backed by epoll, kqueue.
• Zero allocations at runtime
• Non-blocking TCP sockets

Non goals

The following are specifically omitted from MIO and are left to the user or higher level libraries.

• File operations
• Thread pools / multi-threaded event loop

Platforms

Currently, MIO only supports Linux and Darwin. However, Windows support will be coming soon. The goal is to support all platforms that Rust supports.
