Expand description

This trait provides additional functionality to NaiveDate.

Provided Associated Constants§

const MAX_YEAR: i32 = 262_142i32

The maximum year that can be represented by a NaiveDate.

const MIN_YEAR: i32 = -262_143i32

The minimum year that can be represented by a NaiveDate.

Required Methods§

fn today() -> NaiveDate

Returns the current date.

Although this is a static method, it does not return an Option as it cannot fail.

fn days_in_month(&self) -> u32

Returns the number of days in the date’s month.

This method operates on &self. For the equivalent method that operates without an instance, see days_in_month_opt().

§See also

fn days_in_month_opt(year: i32, month: u32) -> Option<u32>

Returns the number of days in the given month.

This method operates without an instance. For the equivalent method that operates on &self, see days_in_month().

The outcome is wrapped in an Option. If the given year or month is invalid, None is returned.

§See also

fn days_in_year(&self) -> u32

Returns the number of days in the date’s year.

This method operates on &self. For the equivalent method that operates without an instance, see days_in_year_opt().

§See also

fn days_in_year_opt(year: i32) -> Option<u32>

Returns the number of days in the given year.

This method operates without an instance. For the equivalent method that operates on &self, see days_in_year().

The outcome is wrapped in an Option. If the given year is invalid, None is returned.

§See also

fn is_leap_year(&self) -> bool

Returns true if the date’s year is a leap year.

This method operates on &self. For the equivalent method that operates without an instance, see is_leap_year_opt().

§See also

is_leap_year_opt()

fn is_leap_year_opt(year: i32) -> Option<bool>

Returns true if the given year is a leap year.

This method operates without an instance. For the equivalent method that operates on &self, see is_leap_year().

The outcome is wrapped in an Option. If the given year is invalid, None is returned.

§See also

is_leap_year()

fn start_of_month(&self) -> NaiveDate

Returns the date of the first day of the date’s month.

This method operates on &self. For the equivalent method that operates without an instance, see start_of_month_opt().

§See also

fn start_of_month_opt(year: i32, month: u32) -> Option<NaiveDate>

Returns the date of the first day of the given month.

This method operates without an instance. For the equivalent method that operates on &self, see start_of_month().

The outcome is wrapped in an Option. If the given year or month is invalid, None is returned.

§See also

fn end_of_month(&self) -> NaiveDate

Returns the date of the last day of the date’s month.

This method operates on &self. For the equivalent method that operates without an instance, see end_of_month_opt().

§See also

fn end_of_month_opt(year: i32, month: u32) -> Option<NaiveDate>

Returns the date of the last day of the given month.

This method operates without an instance. For the equivalent method that operates on &self, see end_of_month().

The outcome is wrapped in an Option. If the given year or month is invalid, None is returned.

§See also

fn start_of_year(&self) -> NaiveDate

Returns the date of the first day of the date’s year.

This method operates on &self. For the equivalent method that operates without an instance, see start_of_year_opt().

§See also

fn start_of_year_opt(year: i32) -> Option<NaiveDate>

Returns the date of the first day of the given year.

This method operates without an instance. For the equivalent method that operates on &self, see start_of_year().

The outcome is wrapped in an Option. If the given year is invalid, None is returned.

§See also

fn end_of_year(&self) -> NaiveDate

Returns the date of the last day of the date’s year.

This method operates on &self. For the equivalent method that operates without an instance, see end_of_year_opt().

§See also

fn end_of_year_opt(year: i32) -> Option<NaiveDate>

Returns the date of the last day of the given year.

This method operates without an instance. For the equivalent method that operates on &self, see end_of_year().

The outcome is wrapped in an Option. If the given year is invalid, None is returned.
