run :: (Expr query, Result r) => RethinkDBHandle -> query -> IO r

Run a given query and return a Result

>>> run h $ num 1 :: IO Int
1

>>> run h $ str "foo" :: IO (Either RethinkDBError Int)

• ** Exception: RethinkDB: Unexpected response: "expected Int, encountered String"

>>> run h $ str "foo" :: IO (Maybe Int)
Nothing

>>> run h $ str "foo" :: IO Int

• ** Exception: RethinkDB: Unexpected response: "expected Int, encountered String"

>>> c <- run h $ table "users" # orderBy [asc "name"] # (!"name"):: IO (Cursor Datum)
>>> next c
Just "bill"
>>> collect c
["bob","nancy"]
