ScalapbJsonImplicits

Opt-in zio-json encoder/decoder bridges for ScalaPB-generated types.

These are needed only when you want zio-json to derive a codec for a generic structure that contains a protobuf type — e.g. JsonEncoder[Either[MyProtobufMsg, String]]. Importing this object brings JsonEncoder[A <: GeneratedMessage] and JsonDecoder[A <: GeneratedMessage] (and the sealed-oneof variants) into implicit scope.

''Do not import globally.'' These encoders/decoders are stubs that must never actually run — the encoder throws, the decoder fails with a Left(msg) decode error — they are meant to live inside a ZTemporalCodec whose actual serialization is handled by ScalapbPayloadConverter earlier in the chain. If they leak into the user's wider zio-json usage (logs, HTTP handlers, etc.) protobuf serialization will fail at runtime.

Import it locally where needed:

 import zio.temporal.protobuf.ScalapbJsonImplicits._
