Struct Date

pub struct Date { /* private fields */ }

A release date for a Rust toolchain.

Nightly toolchains use a date as version instead of a semver number. This Date should be regarded as a form of a version number, just like semver.

For full-featured dates, it is recommended to use a dedicated library like time, chrono or jiff.

Implementations

impl Date

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

Create a new Date instance.

While it is called a date, it is merely a shallow representation of a day in time where a new release was cut. This release date should not be used to perform operations on, and may not even be valid in the Gregorian calendar. For example, a date 0-0-0 will be accepted, but is not a valid month nor year for most parsers which parse a Gregorian date.

It is up to the caller to make sure that the given date is valid. This library just takes a date representation “as-is”.

pub fn year(&self) -> u16

The year

pub fn month(&self) -> u8

The month

pub fn day(&self) -> u8

The day

pub fn ymd(&self) -> impl Display

Prints a yyyy-mm-dd representation of a release date.

This representation may, just like Date, be not a valid date in the Gregorian calendar. The date is merely a representation.

Year, month, and day will all be pre-filled with 0’s. For year, at least four numbers are shown. For month and day, two.

Note that, a representation of 9999-200-200 is still possible, while not valid as a Gregorian date.

Trait Implementations

impl Clone for Date

fn clone(&self) -> Date

Returns a duplicate 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 Hash for Date

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
