pub(crate) fn news_missed() -> Option<(i64, BTreeSet<String>)>Expand description
Whether the last alarm’s exchange on this thread (exchange_here(true))
had no pull go through since it began: then since when, and the devices of
which news came all the same (their entry or health claim, later by its own
times, brought by the sync app). Of the others, what was read before is not taken as knowledge
(sioul_core::health::doubts_unread).
