trait ActionFilter[R[_]] extends ActionRefiner[R, R]
A simple kind of ActionRefiner which, given a request (of type R), may either immediately produce a Result (for example, an error), or continue its Action block with the same request. The critical (abstract) function is filter.

Determine whether to process a request. This is the main method that an ActionFilter has to implement. It can decide to immediately intercept the request and return a Result (Some), or continue processing (None).

Invoke the block.
Invoke the block. This is the main method that an ActionBuilder has to implement, at this stage it can wrap it in any other actions, modify the request object or potentially use a different class to represent the request.
- request
The request

The block of code to invoke

A future of the result
