Add missing template param for StorageInterface

Q	A
Bugfix	yes
BC Break	soft
New Feature	no

Description

Since all laminas cache adapters are extending AbstractStorage, there was already a template TOptions available in that abstract class. Sadly, I forgot to add that to the StorageInterface which is problematic when it comes to interface usage.

This patch adds options template as a bugfix since we do not change any code (besides providing the options generic).

👍 - Out of interest, why do the templates not need to be co-variant?

Out of interest, why do the templates not need to be co-variant?

I have absolutely no clue when it has to be and when not.
I've used covariant once but I cannot remember when. AFAIR covariant is only used if you want to mix stuff such as "pets" where "dog" and "cat" has to be in there.
Storage adapters only provide a single generic and thus covariant is not needed as from how I understand.

But I am not that deep into that stuff as I never really cared 😅
