zio.temporal.internal

Compile-time helpers for auto-registering zio-json codecs from a workflow or activity interface's method signatures.

The macro walks a type I — expected to be a @workflowInterface or @activityInterface — and for every method annotated with @workflowMethod, @signalMethod, @queryMethod, or @activityMethod, summons a ZTemporalCodec[T] for each parameter type and for the return type. If any required codec cannot be summoned, compilation fails with a message pointing at the type that needs one.

The summoned codecs are emitted as runtime registrations into the supplied CodecRegistry. This is what makes CodecRegistry#addInterface[I] work end-to-end: compile-time evidence of codec existence + runtime registration in one call.

The same machinery is used by the ''auto-registration'' path (autoRegisterInterfaceImpl, autoRegisterActivityImplImpl), which is invoked from ZWorker.addWorkflow[I], ZWorker.addActivityImplementation, ZWorkflowClient.newWorkflowStub[A], etc. to remove the need for users to call .addInterface[...] by hand.
