Is there a built-in serializer to "inline" singular-field classes? Example:

@Serializable(InlineSerializer::class)
    class Inlined(val str :String)

   fun main(){
        val obj = Inlined("test")
        val str = json.stringify(Inlined.serializer(),obj)
        assertEquals("\"test\"",str) // And not {"str":"test"}
   }

The tricky part there is when you have to deserialize it, how do you know that it's an Inlined and not just a String.

[Toddobryan]

But to answer your question, I haven't seen one, but it's relatively easy to write. You just do encoder.encodeString(obj.str) in a custom serializer.

Inline classes serialization is not supported at the moment. The compiler throws an exception if you annotate it with Serializable.

Cause: org.jetbrains.kotlin.codegen.ErasedInlineClassBodyCodegen cannot be cast to org.jetbrains.kotlin.codegen.ImplementationBodyCodegen

@Toddobryan That's what I did 🙂 I made it generic though so It's a bit more complicated
@Paulius Ruminas Not quite what I meant

Oh you did not use the inline modifier I did not see that.
