pub fn revoke_feed(
conn: &Connection,
feed_id: &str,
actor_user_id: &str,
is_owner: bool,
) -> Result<bool, String>Expand description
Revokes a feed. An owner may revoke any feed; a sub-user only their own — enforced here rather than trusted to the caller, since this is the one place that decides whether a URL someone thought they killed still works.
