Does the tracing crate support logs rate limiting? (lemmy.ml)

I've been reading a bit the tracing crate documentation, trying to find out if there's a way to rate limit logs.

What I refer with rate limiting, is that once a particular log has shown up with some frequency (x amount of times in a given time) then it won't be captured or shown anymore, until certain amount of time... This to avoid getting the logs space/buffer being eaten by just one, or a few high frequency errors for example.

Thanks !

Yeap, I was thinking if perhaps any subscriber would support it, but didn't find any which documents it. Perhaps you're right and subscriber wrapper is needed.

    One thing to keep in mind is that tracing works on spans/events, so rather than the subscriber receiving a string log message, it's receiving some metadata and a collection of field/value pairs, where values can be a lot of different types. You may need to determine ahead of time which fields you want deduped (or which you don't want deduped).
