Our company have rust based gateway, try to add quic/http3 on it. So I am researching a Rust QUIC library(quinn/msquic/s2n/quiche/quictls) to integrate it into the gateway.

You may know this issue. I solved by patch rustls. https://github.com/rustls/rustls/issues/1976. since it cause breaking api change. I haven't submit PR. I prefer use quic library which can integrate rustls...

I don't know too much inner detail about metrics. No idea how to build from inner type. But other codes should correct.

If we shouldn't include runtime timeout/sleep, how we implement timeout mechanism
