I'm using this kind of map customSerializers: Map<KClass<*>, KSerializer<*>>. In 0.20.0 I've used this function, which is now deprecated:

@Deprecated(
    level = DeprecationLevel.ERROR,
    message = "This method was removed during serialization 1.0 API stabilization, " +
            "please use SerializersModule builder instead" // No replacement deliberately
)
public fun serializersModuleOf(map: Map<KClass<*>, KSerializer<*>>): SerializersModule = noImpl()

How to use SerializersModule builder to create a SerializersModule from my customSerializers map?

[Robert Jaros]

I've tried this:

Json {
                    serializersModule = SerializersModule {
                        customSerializers?.map {
                            contextual(it.key, it.value)
                        }
                    }
                }

but it does not compile.

The function was implemented this way in 0.20:

map.forEach { (kclass, serializer) -> contextual(kclass as KClass<Any>, serializer.cast()) }

But what was .cast() method/function doing? It's not available now.

[Robert Jaros]

Should I just cast serializer as KSerializer<Any>?

Yes, it should work that way
