I have this data class ``` Serializable data class ApiResponse lt T gt Serializable with = HttpStatusCodeSerializer class val code HttpStatusCode val errors List lt KlubberError gt = emptyList val data T ``` Does it make sense to use a type `ApiResponse lt Nothing gt ` in case of errors And what should I pass for the `data` parameter ```val response = ApiResponse lt Nothing gt code = myCode errors = listOf error1 error2 data = lt what should I use here gt ``` Using Unit instead of Nothing allows me to write `data = Unit` is that a better approach

I have this data class ``` Serializable data class ApiRespon kotlinlang #getting-started

I have this data class

@Serializable
data class ApiResponse<T> (

    @Serializable(with = HttpStatusCodeSerializer::class)
    val code: HttpStatusCode,

    val errors: List<KlubberError> = emptyList(),
    val data: T,
)

Does it make sense to use a type

ApiResponse<Nothing>

in case of errors? And what should I pass for the

data

val response = ApiResponse<Nothing> (
    code = myCode,
    errors = listOf(error1, error2),
    data = <what should I use here?>,
)

Using Unit instead of Nothing allows me to write

data = Unit

is that a better approach?

sealed class ApiResponse {
	abstract val code: HttpStatusCode,

	data class StandardResponse<T>(
		override val code: HttpStatusCode,
		val data: T,
	) : ApiResponse()

	data class ErrorResponse(
		override val code: HttpStatusCode,
		val errors: List<KluberrError>,
	) : ApiResponse()
}

maybe something like this?

val data: T?

@Paul Griffith yeah I guess I’ll go with that design, I guess not having the

error

property at all in case of success is a good thing
