Struct Date 

pub struct Date(/* private fields */);

A calendar date, stored as days since Unix epoch (1970-01-01).

Range: roughly year -5,879,610 to +5,879,610.

Examples

use grafeo_common::types::Date;

let d = Date::from_ymd(2024, 3, 15).unwrap();
assert_eq!(d.year(), 2024);
assert_eq!(d.month(), 3);
assert_eq!(d.day(), 15);
assert_eq!(d.to_string(), "2024-03-15");

Implementations

impl Date

pub fn from_ymd(year: i32, month: u32, day: u32) -> Option<Self>

Creates a date from year, month (1-12), and day (1-31).

Returns None if the components are out of range.

pub const fn from_days(days: i32) -> Self

Creates a date from days since Unix epoch.

pub const fn as_days(self) -> i32

Returns the number of days since Unix epoch.

pub fn year(self) -> i32

Returns the year component.

pub fn month(self) -> u32

Returns the month component (1-12).

pub fn day(self) -> u32

Returns the day component (1-31).

pub fn to_ymd(self) -> (i32, u32, u32)

Returns (year, month, day) components.

pub fn parse(s: &str) -> Option<Self>

Parses a date from ISO 8601 format “YYYY-MM-DD”.

pub fn today() -> Self

Returns today’s date (UTC).

pub fn to_timestamp(self) -> Timestamp

Converts this date to a timestamp at midnight UTC.

pub fn add_duration(self, dur: &Duration) -> Self

Adds a duration to this date.

Month components are added first (clamping day to month’s max), then day components.

pub fn sub_duration(self, dur: &Duration) -> Self

Subtracts a duration from this 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 Default for Date

fn default() -> Date

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Date

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Date

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

Formats the value using the given formatter.

impl From<Date> for Value

fn from(d: Date) -> Self

Converts to this type from the input type.

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.

impl Serialize for Date

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
