PHP Class Zend\Expressive\ErrorMiddlewarePipe
Normal MiddlewarePipe implementations implement Zend\Stratigility\MiddlewareInterface,
which can be consumed as normal middleware, but not as error middleware, as
the signature for error middleware differs.
This class wraps a MiddlewarePipe, and consumes its internal pipeline
within a functor signature that works for error middleware.
It is not implemented as an extension of MiddlewarePipe, as that class
implements the MiddlewareInterface, which prevents its use as error
middleware.

Zend\Stratigility\MiddlewarePipe |
|
This is essentially a version of the MiddlewarePipe that acts as a pipeline
for solely error middleware; it's primary use case is to allow configuring
arrays of error middleware as a single pipeline.
Operation is identical to MiddlewarePipe, with the single exception that
$next is called with the $error argument.
