fn parse_years_range(s: &str, valid_years: &[u32]) -> Result<Vec<u32>>Expand description
Parse a year string that is defined as a range, selecting the valid years within that range.
It should be of the form start..end. If either of the limits are omitted, they will default to
the first and last years of the valid_years. If both limits are missing, this is equivalent to
passing all.
