pub fn prose(response: &Json, asked: &Article) -> Option<Prose>Expand description
The paragraph, credited, from a REST summary document.
None when the page holds no extract — a disambiguation page, a redirect
to one, a stub that is only an infobox — which is not an error: it is the
same “asked, and there is nothing” the rest of the layer records.
The URL stored is the article’s own canonical address when the response
gives one, and the address that was asked otherwise. It is never left out:
a Prose cannot be built without it, which is the point of the type.
