Build Diagnostics

The source generator checks your actors as you build, so mistakes surface in the IDE instead of at runtime.

Code
SACT001	An interface member can’t be proxied (a property, a generic method, or ref/out/in parameters)
SACT002	A method doesn’t return Task, Task<T>, ValueTask or ValueTask<T>
SACT003	A [OneWay] method returns a value
SACT004	A class implements an actor interface but doesn’t derive from Actor
SACT005	An actor can’t be constructed (it’s generic, private, or has ambiguous constructors)
SACT006	Warning: two classes implement one interface. Pick one with actors.AddActor<IFoo, Foo>()
SACT007	Warning: a state or event type (Actor<T>, JournaledActor<,>, [ActorState]) isn’t on any JsonSerializerContext
SACT008	An actor interface is generic or not reachable
SACT009	Two actors share an [ActorName]
SACT010	An [ActorState] parameter isn’t an IActorState<T>
SACT011	A [StatelessWorker] has persistent state (Actor<T>, JournaledActor<,> or [ActorState])

What the generator writes

For each actor interface, it writes a local proxy, a remote proxy and a wire contract. For each class, it writes a registration. A single module initializer wires all of it up, which is why AddShinyActors() needs no list of actors and nothing is found by reflection.
