Use @JsonCreator with vavr validation?

[smarijic]

Hi,

Is there a way to return Try from static factory annotated with @JsonCreator?
Here is question on SO. https://stackoverflow.com/questions/53917859/jackson-jsoncreator-return-generics

Thanks.

I think this is not supported by Vavr Jackson yet. Returning Try<T> instead of T requires new serializer and deserializer. The deserializer will be able to modify the existing type T and encapsulate it into Try<T>, in both success and failure cases. However, this is a completely new feature. What do you think, @ruslansennov and @danieldietrich ?

I believe a simplified version of @smarijic 's request is:

Try<FooCommand> cmd = mapper.readValue(json, new TypeReference<Try<FooCommand>>() {});

Looks like Option, and can be implemented in the same ugly way. But I believe that these new serializer and deserializer have more rights to life than mutable Iterator (see #130)

Thank you, @ruslansennov . Could you give some additional hints about the changes to make? I didn't fully understand the exception shown at issue 130. I'll take a look in the coming days and get back to you.
