Get Defined Properties/Keys

[trevorh]

Hi,

I just came across your gem as a replacement for Hashie::Mash w/ StrictKeyAccess enabled. I've been having some odd issues that others have had as well.

ROS seems like almost a perfect fit, but I have no way to easily introspect the properties/keys of an object. When I have raise_on_missing: enabled, I really would like to be able check for the presence of a key without resorting to respond_to?.

Specifically, I'm using this with Faraday and am trying out my own middleware based on the Mashify middleware but renamed to Rosify obviously :) . Essentially, it converts any response body to a ROS object when possible.

To get the list of keys I've added a refinement to use when I need it.

  refine RecursiveOpenStruct do
    def _struct_keys
      @table.keys
    end
  end

Is there anything I'm missing or why I shouldn't do something like this?

Thanks!
