how to use pprof-rs in async-program #120

is there any way to support async-program, ex. tokio

Did you get an answer? I also need specific functions in async context.

Strange to say, some function (e.g. BytesMut::clone()) was appeared, so I wonder what's difference. (Same code with non-async context appeared correctly)

I'm not sure my theory is correct or not, but from my understanding about the cpu sampling behavior, async function called via poll() may not be captured as it's just one very short function call :thinking:
