pub fn millis_from_iso8601(text: &str) -> Option<i64>Expand description
Parse an ISO 8601 UTC timestamp back to epoch milliseconds. Accepts both the
fixed-width YYYY-MM-DDTHH:MM:SSZ form iso8601 emits and a fractional
…:SS.fffZ form (only the leading three fraction digits are kept). Returns
None unless the shape is a date T time split with in-range fields; the
fraction is scanned with chars() so untrusted multibyte input never panics.
