Query

io.eezo.db.Query
See theQuery companion object
final case class Query[T](table: Table[T], pred: Expr[T] = ..., ord: List[Order[T]] = ..., lim: Option[Int] = ..., off: Option[Int] = ...)

A query, as a pure description. DESIGN §9.3.

It holds no capability, so it can be built anywhere, passed around, composed conditionally and unit-tested without a database. Only the terminals require DB, and they are strict — there is no cursor here to outlive the scope that produced it.
