Description
actually, nothing special about this implementation. just another event loop written in rust for educational purposes and joyin tests it shows seamless migration from uvloop for my scraping framework https://github.com/BitingSnakes/silkwormwith APIs (fastapi) it shows only one advantage: better p99, uvloop is faster about 10-20% in the synthetic runcurrently, i am forking on the win branch to give it windows support that uvloop lacks

Could you build this?
No Writing a custom Python asyncio event loop in Rust requires deep systems programming knowledge of epoll/kqueue, OS syscalls, and Python's complex C-API/PyO3 internals.
What it would actually take: Requires deep CPython C-API internals, PyO3/Maturin bindings, and cross-platform asynchronous I/O syscalls (epoll, kqueue, io_uring via mio/tokio). The developer must safely manage Python GIL interactions, asynchronous task scheduling, exception handling, and socket management to meet or exceed C-based uvloop performance.
