I want to Cbor.dump a class and I need to pass TestClass.serializer(), but the type I receive is Any, is there a way to get that TestClass.serializer() at runtime without testing the type with when/is? But it looks like to me there is no way to do that as .dump requires the <T> at compile time

There is an extension function

dump(obj: T)

on

BinaryFormat

that uses reflection to find the serializer.

if I do that I get an exception

Ah, yeah, you need the actual class... You can maybe use

context.getContextualOrDefault(value::class)

as the serializer

Yes you need an unsafe cast to

SerializationStrategy<Any>

it worked, jeez

No, never have 😄

I asked myself, I get an Any but the type at runtime is known, why woudn't this work

reified

is a compile-time thing

that yes and actively using it successfully

BinaryFormat.dump(obj: T)

has

T

reified. Since the compiler infers

Any

for

T

, it will use

Any::class

for the serializer lookup.

ah ok but we are using the other dump overload function:

Yes, now we are.

ok

Yes

hey how do u get the flag by your username?

Yes, thats my status message

I see
