Instance Method Details

#call(env = nil)

This method is for internal use only.

AUTHORS: n.b. The trailing whitespace between paragraphs is important and should not be removed. The whitespace creates paragraphs in the RDoc output.

This specification aims to formalize the ::Rack protocol. You can (and should) use Lint to enforce it.

When you develop middleware, be sure to add a Lint before and after to catch all mistakes.
