Is there way to ergonomically get a tuple from a checked query?

[Victor-N-Suadicani]

I find myself writing something like this often:

let (name, title) = query!(
    "select name, title from users where id = $1",
    user_id
)
.map(|r| (r.name, r.title))
.fetch_one(&mut **tx)
.await?;

Is there a way to avoid that .map call and get a tuple directly? I know I can do it with the query_as function, but then I don't get the query checked at compile time and I must specify the types myself. query_scalar doesn't work as it only works for single columns. It feels like there might be a missing query_tup! macro which could do this? Or is there some limitation explaining why this is not implemented? I.e. I'd like this interface:

let (name, title) = query_tup!(
    "select name, title from users where id = $1",
    user_id
)
.fetch_one(&mut **tx)
.await?

If you need a structure you can pass around, it'd make for more readable code if you just defined a struct and used query_as!().
