fn is_month_forbidden(&self, year_month_info: &NaiveDate) -> bool
Returns true if the entire month described by year_month_info is forbidden.
Sourcefn is_year_forbidden(&self, year: i32) -> bool
fn is_year_forbidden(&self, year: i32) -> bool
Returns true if the entire given year is forbidden.
Sourcefn is_year_group_forbidden(&self, year: i32) -> bool
fn is_year_group_forbidden(&self, year: i32) -> bool
