pub fn parse_millis_to_nanos(millis: u64) -> Result<UnixNanos>Expand description
Converts a Unix millisecond timestamp into [UnixNanos].
ยงErrors
Returns an error if millis * 1_000_000 would overflow u64. Realistic
venue timestamps are nowhere near this bound; the check rejects malformed
payloads instead of silently wrapping in release builds.
