pub fn limits_of<'a>(
outcomes: &'a [Outcome],
phone: &str,
now_ms: i64,
) -> Option<(i64, &'a [Limits])>Expand description
What a phone last said its carriers let it send (its newest “limits”
line), and when (ms); none before it said. A line dated more than
LIMITS_AHEAD_MS ahead of now_ms (the reader’s clock) is passed over:
a phone whose clock was once set ahead would otherwise be read by it
until that date, whatever it said since.
