data class SomeModel(val id: String, val name: String)

interface SomeModelRepository {
    suspend fun getSomeModels(): Answer<List<SomeModel>, String>
}

interface GetSomeModelUseCase {
    suspend operator fun invoke(): Answer<List<SomeModel>, String>
}

class GetSomeModelUseCaseImpl(
    private val someModelRepository: SomeModelRepository
) : GetSomeModelUseCase {
    override suspend fun invoke() = someModelRepository.getSomeModels()
}

class SomeViewModel(private val getSomeModelUseCase: GetSomeModelUseCase) : ViewModel() {
    fun load() {
        viewModelScope.launch {
            val result = getSomeModelUseCase()
            // Do something with the result
