Missing type definitions for cast method

[cajoy]

Describe the bug

I am trying to cast on subscription recurly.Subscription.cast(...) but getting following error:

Property 'cast' does not exist on type 'typeof Subscription'.

Expected behavior

Should be no typescript errors

Your Environment

3.18.0

Thank you for creating an issue, @cajoy.

This cast method is intended to be an internal method for casting an API response into a Resource. There shouldn't be any need to invoke it directly. What is your use case for making use of the cast method directly?

[cajoy]

Why using it for testing.

I see your point. If it meant to be internal then we can do something like

(recurly.Subscription as any).cast(...)

But would be better if still can be exposed via interface
