set_florb() is documented as "Sets the florb"

Doc comments for Hub methods don't contain information, e.g.

https://getsentry.github.io/sentry-rust/sentry/struct.Scope.html#method.set_transaction

set_transaction says "Sets the transaction.", but this adds 0 information beyond the method name. What are transactions? Why would I use them? What happens if I don't set any?

I have a feeling that these are standard Sentry terms documented somewhere else, but since I'm adding Sentry to a Rust project, this is the first time I see these terms, and I'm lost.
