pub fn entity_id(url: &str) -> Option<String>Expand description
The Wikidata entity id inside a URL MusicBrainz returned.
MusicBrainz gives the relationship as a page URL rather than a bare id, and
it does not always give the same one: www.wikidata.org/wiki/Q11649 is the
usual shape, but the entity URI .../entity/Q11649 appears too. Both end
in the id, so the id is read from the end rather than the middle.
Returns None for anything that does not end in an entity id, which is the
honest answer for a link that leads somewhere else — a lexeme, a property,
or a URL that was never Wikidata at all.
