pub fn parse(raw: &str) -> Option<Timestamp>Expand description
Read one of the date spellings a vault may hold.
Accepted: YYYY-MM-DD, optionally followed by T or a space and
HH:MM[:SS], optionally followed by Z or ±HH[:]MM. Trailing fractional
seconds are read and dropped — neither output grammar carries them.
None for anything else, including a well-formed string naming a day that
does not exist (2026-02-30): a date that cannot be placed on a calendar
cannot be given a weekday, and RFC 822 needs one.
