sealed trait BasicMeta[A] extends Meta[A]

Meta for "basic" JDBC types as defined by the specification. These include the basic numeric and text types with distinct get/setXXX methods and fixed mappings that ostensibly work for all compliant drivers. These types defined both "recommended" source types (jdbcSource here) and "supported" types (jdbcSourceSecondary) which drivers must not reject outright, although in many cases coercion failures are likely (reading an Int from a VarChar for instance) so these mappings should be viewed with suspicion.

    Invariant map (note that you must handle null; see nxmap). Meta is not quite an invariant functor because of the tag constraint, but I think it's worth the sacrifice because we get much better diagnostic information as a result.
