Struct Date 

pub struct Date { /* private fields */ }

A date value representing a calendar date (year, month, day) without time information. Always interpreted in SVTC.

Internally stored as days since Unix epoch (1970-01-01).

Implementations

impl Date

pub fn is_leap_year(year: i32) -> bool

Check if a year is a leap year

pub fn days_in_month(year: i32, month: u32) -> u32

Get the number of days in a month

impl Date

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

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

pub fn today() -> Self

pub fn year(&self) -> i32

pub fn month(&self) -> u32

pub fn day(&self) -> u32

pub fn to_days_since_epoch(&self) -> i32

pub fn from_days_since_epoch(days: i32) -> Option<Self>

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() -> Self

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 GetType for Date

fn get_type() -> 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 IntoValue for Date

fn into_value(self) -> Value

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.

impl TryFromValue for Date

fn try_from_value(value: &Value) -> Result<Self, FromValueError>

Attempt to extract a value of this type from a Value.

fn from_value(value: &Value) -> Option<Self>

Extract from Value, returning None for Undefined or type mismatch.
