Google has quietly added a "rich result" filter in the Google Search Console's Search Analytics report. You can now click on search appearance filters and select "rich result" to filter out the Google impressions and clicks you get specifically for rich cards, rich snippets and other rich results within the Google search results.
Here are two screen shots from my search console screen:
This works just like the AMP filter in Search Analytics. We knew this was coming, we saw screen shots from Googlers for featured snippets and rich results in the Search Analytics report back at Google I/O.
And now it is there. These filters are really nice and give us a way to break down our search impressions and clicks within Search Analytics.
