What type should I be putting in

???

such that

toResult

won’t error? I’ve tried

Nothing

and it is not working

sealed class ApiResult<T>

data class Success<T>(
    val msg: String,
    val data: T
) : ApiResult<T>()

data class Failure(
    val error: String,
    val errMsg: String
) : ApiResult<???>()

fun toResult(): ApiResult<User> {
        return if (error == "0") Success(
            msg = msg, data = movies
        ) else Failure(error = error, errMsg = errMsg)
    }

Unit

maybe?

Make

T

covariant by marking it with

out

. Then

Nothing

should work.

out

trick works!! Thanks

No problem

Shouldn't you just remove the type parameter on ApiResult, and keep it on Success?
