# serialization

[Rainer Schlonvoigt]

Probably a stupid question, but googling doesn’t get me anywhere 😕
Can i easily use

@Serializable(with=...)

on a Set of a custom class?

More specifically, my scenario looks like this:

@Serializable
data class MyClass(
    @Serializable(with=???)
    val mySet: Set<UUID>
)

where UUID is from java.util so i can’t annotate it

i did write a KSerializer for UUID, but is there a cheap way to make it work with the Set?

I think @file:UseSerializers(YourUUIDSerializer::class) would be easiest

[Rainer Schlonvoigt]

oh, didn’t know that one, yet

[Rainer Schlonvoigt]

thank you, will give it a try! 🙂

val mySet: Set<@Serializable(with = MyUuidSerializer::class) UUID> should work too, but @file:UseSerializers() is easier if you have more than one instance in the file

[Rainer Schlonvoigt]

it works! thank you guys
