PTAL @LyricZhao @wyfcyx. Thanks!

I left a comment about reproducing the issue at https://github.com/vectordotdev/vector/issues/13467#issuecomment-1273114470. I ran it with this patch, and the problem seems resolved, cc @sillent @spencergilbert

I have steps to reproduce the problem. Hope it helps. Arch: x86_64 OS: Ubuntu 20.04 1. Install `minikube` & `helm` ``` curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 sudo install minikube-linux-amd64 /usr/local/bin/minikube minikube start...

Just like the previous example, for toml file, I specify it like this: ```toml [b] ```

The scenarios that cause `B` to be lost are related to iterators. An example that better reflects the situation I found: ```rust #[derive(Debug, Serialize, Deserialize, PartialEq)] struct A { b_option:...

By reversing your initial thought, we might be able to realize performance gains: minitrace is in charge of span generation, and tokio-tracing collects the spans produced by minitrace.

So low-overhead cannot be achieved. Are there any scenarios for this requirement?
