# serialization

Is there a way to accept Serializable types in a function? Like some supertypes or something?
Usecase:

fun <T : Any> store(key: String, value: T, serializer: KSerializer<T>) {
    json.stringify(serializer, value)
}

//To, maybe reified
fun <T : SomeSuperTypeForSerializable> store(key: String, value: T) {
    json.stringify(T.serializer(), value)
}

Found out myself, used reflections here, althrough use is discouraged, it looks cleaner, because they are inferred

[Animesh Sahu]

inline fun <reified T: Any> store(key: String, value: T) {
    val serializer = T::class.serializer()
}

but that only works on jvm, passing the serializer around would work on other platforms too (most likely)

JVM is most stable so, atleast work there😜

Better than nothing :V

Would be really nice, but I think it would get quite complicated in Kotlin as it is right now, because the compiler wouldn't just need to know that T implements some interface that declares serializer(), it would in fact need to assert that T has a companion object that implements such an interface.

This is one of those areas where C++ templates really shine.

well it could also just look for a annotation on the class @Serializable(with=...) assuming the compiler can modify the annotation when it injects all the serializable stuff
that would at least only be a single marker on the type to match
