Show HN: An event loop for asyncio written in Rust (opens in new tab)

actually, nothing special about this implementation. just another event loop written in rust for educational purposes and joy

in tests it shows seamless migration from uvloop for my scraping framework https://github.com/BitingSnakes/silkworm

with APIs (fastapi) it shows only one advantage: better p99, uvloop is faster about 10-20% in the synthetic run

currently, i am forking on the win branch to give it windows support that uvloop lacks

The p99 improvement over raw throughput matches what I've seen with napi-rs too — Rust's predictable memory management helps with tail latencies even when average perf is similar to C implementations. Windows support gap for uvloop is a real pain point in production, so that alone could justify the switch for some teams.

when i was building silkworm, unability of uvloop to support Windows was a problem for me, so i added winloop

btw, they seem to be included into uvloop: https://github.com/Vizonex/Winloop/commit/317873329143e8cf82...

added support for Windows in v0.1.3
