pub fn parse_wind_direction_standalone(
token: &str,
) -> Result<ParsedWindDirection, WindDirectionParseError>Expand description
parse_wind_direction for STANDALONE flag contexts (--wind-direction), which
additionally accept the <H>:<MM> colon clock form (10:30 = 315°) — legal there
because a flag value is never colon-delimited grammar (MBA-1367).
