Struct Date 

pub struct Date { /* private fields */ }

A calendar date. Construction validates it, so every Date exists.

Implementations

impl Date

pub fn new(year: i32, month: u8, day: u8) -> Result<Self, InvalidDate>

A date from its parts.

Errors

Returns InvalidDate for a month outside 1–12 or a day the month lacks, or a year outside 1–9999, which ISO strings cannot write in four digits.

pub fn parse(iso: &str) -> Result<Self, InvalidDate>

Parse YYYY-MM-DD.

Errors

Returns InvalidDate for any other shape or a date that does not exist.

pub const fn year(self) -> i32

The year.

pub const fn month(self) -> u8

The month, 1–12.

pub const fn day(self) -> u8

The day of the month.

pub fn to_days(self) -> i64

Days since 1970-01-01.

pub fn from_days(days: i64) -> Option<Self>

The date days since 1970-01-01, or None outside years 1–9999.

pub fn add_days(self, delta: i64) -> Option<Self>

The date delta days away, or None past the representable range.

pub fn weekday(self) -> u8

Day of the week, 0 = Sunday … 6 = Saturday.

pub fn add_months(self, delta: i32) -> Option<Self>

The same day delta months away, clamped to that month’s length, as upstream’s addMonths.

use fc_dioxus::behavior::date::Date;
let Ok(jan31) = Date::parse("2026-01-31") else { return };
assert_eq!(jan31.add_months(1).map(|d| d.to_string()), Some("2026-02-28".into()));
assert_eq!(jan31.add_months(-13).map(|d| d.to_string()), Some("2024-12-31".into()));

pub fn first_of_month(self) -> Self

The first of this date’s month.

impl Ord for Date

fn cmp(&self, other: &Self) -> 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.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Date

fn partial_cmp(&self, other: &Self) -> 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
