如何在kotlin中使密封类成为泛型？

sealed class Result<out T>

data class Success<T>(val data: T) : Result<T>()
data class Error(val message: String) : Result<Nothing>()

fun <T> processResult(result: Result<T>) {
    when (result) {
        is Success -> {
            val data: T = result.data
            // 处理成功结果
        }
        is Error -> {
            val message: String = result.message
            // 处理错误结果
        }
    }
}

fun main() {
    val successResult: Result<Int> = Success(42)
    val errorResult: Result<Nothing> = Error("Something went wrong")
    
    processResult(successResult)
    processResult(errorResult)
}
