Struct Date

pub struct Date {
    pub year: u16,
    pub month: u8,
    pub day: u8,
}

Indicates the date.

Used for the nightly versions of rust.

The timezone is not explicitly specified here, and matches whatever one the rust team uses for nightly releases.

Fields

year: u16

The year

month: u8

The month

day: u8

The day of the month.

Implementations

impl Date

pub const fn new(year: u16, month: u8, day: u8) -> Self

Create a date, using YYYY-MM-DD format (ISO 8601).

For example, Date::new(2018, 10, 21)

If possible, perform some basic validation.

TODO: Don’t make this a const fn function, because doing validation is more important.

pub const fn is_since(&self, start: Date) -> bool

Check if this date is equal to or after the specified start.

Equivalent to self >= start, but available as a const function.

Example

assert!(Date::new(2024, 11, 16).is_since(Date::new(2024, 7, 28)));

pub const fn is_before(&self, end: Date) -> bool

Check if this date is before the specified end.

Equivalent to self < end, but available as a const function.

Example

assert!(Date::new(2018, 12, 14).is_before(Date::new(2022, 8, 16)));
assert!(Date::new(2024, 11, 14).is_before(Date::new(2024, 12, 7)));
assert!(Date::new(2024, 11, 14).is_before(Date::new(2024, 11, 17)));

Trait Implementations

impl Clone for Date

fn clone(&self) -> Date

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Date

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Date

Displays the date consistent with the ISO 8601 standard.

fn fmt(&self, formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Ord for Date

fn cmp(&self, other: &Date) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Date

fn eq(&self, other: &Date) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Date

fn partial_cmp(&self, other: &Date) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
