how to run many query futures concurrently in a Transaction?

[sify21]

Currently I'm using a Transaction with multiple successive .await calls, but I think there must be a way to run those futures concurrently, I just don't know how.

I tried to do it using FuturesUnordered. The problem I'm facing is that Executor is only implemented for &mut Transaction, and Transaction doesn't implement Copy or Clone, this means those futures must take multiple mutable reference to one Transaction, which is not allowed.

I saw #408, it seems what I want is pipeline mode which is a feature of the database, and I can't achive it with something like futures::stream::futures_unordered::FuturesUnordered. Am I right?
