Middleware use case with callable/variadic types

[melya]

Consider I have a use-case with rate limiting middleware for any invokable service.

Preconditions:

• each service could have (and obviously should 😄) it's own function signature.
• middleware should return same result as invoked service

How can I handle this with phpstan?

Example: https://phpstan.org/r/460c72aa-1dd7-42a5-ad80-0ab49fa1dffe
Note: Middleware doesn't handle tries exceed case, but it doesn't important here

Looking forward for any help, thanks!

Hi, this is how you get rid of the PHPDoc parse error https://phpstan.org/r/2e6a16d4-033d-433b-9b0a-33e384164c07 (see the docs https://phpstan.org/writing-php-code/phpdoc-types#callables), but variadics in generics aren't supported yet.

Thanks for the response!
I made a mistake intentionally to show how I would like to configure typings.

I see

variadics in generics aren't supported yet

Do you consider to implement it and have any deadlines for this feature?
Will appreciate if you link an feature request so I can follow it 🙌

*Can imagine that those implementation is not trivial at all 🙈
