Propagate tracing span attributes in sentry events

[samscott89]

Hey,

Thanks for providing Rust support. We're happily using sentry and sentry-tracing crates. Mostly all working well.

We expose a ton of helpful debugging information through span attributes. As far as I can tell, these are captured for performance monitoring, but aren't provided as context when capturing events (via tracing::error! for example).

Is there any way that any span data captured could also be included in events emitted by sentry-tracing?

I don’t think this is currently possible. Other members of the team are prototyping ways to rewamp the performance monitoring / tracing APIs to make such things easier in the future, but it is still very early in that process.

Cool, looking forward to seeing what happens there. Let me know if you want any feedback/testers, we'd be open to trying stuff out.

Hello. I just made the implementation of this feature. Would be glad if someone look at it and maybe suggest some improvements.
