Probably a stupid question, but googling doesn’t get me anywhere :confused:
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&lt;UUID&gt;
) ```
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

thank you, will give it a try! :slightly_smiling_face:

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