pub fn parse_datetime_ns(s: &str) -> Result<u64, FilterError>Expand description
Parse an RFC 3339 datetime string or a Unix epoch integer (in seconds) to nanoseconds since the Unix epoch.
Bare integers are treated as whole seconds, which is the dominant convention
(date +%s, Python time.time(), etc.). Sub-second precision requires an
RFC 3339 string with a fractional seconds component.
ยงErrors
Returns FilterError::InvalidDateTime if the string is neither a valid
RFC 3339 string nor a decimal integer.
