Any short way to inject a child of:

interface UseCase<in Request : Any> {
    suspend fun execute(request: Request): ServerResponse

    suspend operator fun invoke(request: Request): ServerResponse = execute(request)
}

in a ktor fun Route.someRoutes() using the `Request`'s type? I want to be able to provide an implementation in Unit tests without mocking the actual implementation for that route... and the Request object is unique for each UseCase...

Does this make sense @arnaud.giuliani?

inline fun <reified Request : Any> Route.injectUseCaseByRequestType(
    noinline parameters: ParametersDefinition? = null
) = inject<UseCase<Request>>(qualifier<Request>(), parameters)

inline fun <reified Request : Any> Module.singleUseCase(
    createdAtStart: Boolean = false,
    override: Boolean = false,
    noinline definition: Definition<UseCase<Request>>
): BeanDefinition<UseCase<Request>> = single(qualifier<Request>(), createdAtStart, override, definition)

inline fun <reified Request : Any> Scope.getUseCase(
    noinline parameters: ParametersDefinition? = null
): UseCase<Request> {
    return get(UseCase::class, qualifier<Request>(), parameters)
}

yep, seems ok 👌

Thanks for double checking 🙂, I'm a bit new to Koin -- I wasn't sure I was doing this the right way.
