io.getquill.context.cassandra.encoding

MappedTypes contains implicit CassandraMapper for Scala primitive/common types which are not in relation with CassandraTypes but can be represented as ones.

Developers API.

End-users should rely on MappedEncoding since it's more general.

Marker which signals that type T is already supported by Cassandra

CassandraTypes contains implicit markers for already supported types by Cassandra. Any of this type can be used in raw encoders/decoders as well as in collections encoding. For custom types please use MappedEncoding as in MappedTypes trait for example.

UdtDecoding and UdtEncoding classes govern implicit summoning of Udt Encoders/Decoders. Unlike Scala2-Quill, in ProtoQuill these need to be separate classes since if would have encoders & decoders in one, Encoders self-type would also need to to contain decoders. Also note that because I have decided to allow the types Decoder[_], Encoder[_] to be parameters, despite the fact that really it is CassandraEncoder and CassandraDecoder that are used everywhere. This is to allow future Cassandra context implementations not to have to use that. Also, note that just like EncodingDsl.anyValEncoder/Decoder, this implementation is subject to the problem of https://github.com/lampepfl/dotty/issues/12179 and therefore needs to have the same workaround i.e. having the macro call returning a CassandraDecoderMaker[Decoder, T] => Decoder[T] as opposed to being able to use self.decoder/encoder in the macro directly.
