final class From[A] extends Serializable

Special container which is holds query input values. It's used to properly represent a result of joins, flatMaps, etc.

Example:

val joined: Query[From[Employee] with From[Company], (Employee, Company)] =
  select[Employee]
    .join(select[Company])
    .on(_.companyId == _.id)

scalaql uses From to get appropriate input values based on their type.

Based on original idea of ZIO authors (zio.Has)
