A modern programming language that makes developers happier.

kotlinlang

Is it possible to create an interface which requires one of its properties to be `@Serializable`? Or `@Contextual`? Ideally it would be a compile-time exception if the contract wasn't followed, but not the end of the world if its a runtime problem.

You could ask for a serialiser in the interface I guess.

Do you want the any of the interface realisation to be serialisable also?

Probably not, otherwise it will be just for free

Right, no on the interface implementation itself

Sounds like you want to write a lint rule for that
