Is serializing anonymous objects supported in kotlinx serialization? something like:

@Serializable object {
    val message = "some message"
}

Seems to throw an internal error

Yeah, if you look at most of the serializable functions from the library, they require specific type parameters. So yeah, this wouldn't make sense for an anonymous object

[ephemient]

how would it be deserialized?

[Jason Ankers]

Presumably the same way it would be deserialized if it were an explicit type

[bsimmons]

^^ I think that was a rhetorical question.

😉

[Jason Ankers]

Why would it be rhetorical lol

[ephemient]

serious question, in terms of "have you thought through everything that's involved"

[ephemient]

@Serializable generates a KSerializer that performs both serialization and deserialization. the descriptor here needs to have a SerialName (even if you don't use it, because some formats do), the object here also does not have a constructor that a deserializer can invoke, and it definitely can't work if it captures anything
