pub fn parse_duration_string(s: &str) -> Option<Duration>Expand description
v0.7.0 (issue #518) — parse a duration string of the form
"<integer><unit>" into a chrono::Duration. Supported units:
s (seconds), m (minutes), h (hours), d (days), w (weeks).
Whitespace and case are tolerated. Returns None on malformed
input — the caller falls through to “no since filter applied”.
Intentionally a small bespoke parser rather than a humantime
dependency: the surface we need is tiny (4-5 units) and operators
expect the same shape they already type into --since flags.
