Struct Date 

#[non_exhaustive]
pub struct Date {
    pub day: Option<i32>,
    pub month: Option<i32>,
    pub year: Option<i32>,
    /* private fields */
}

Available on crate feature preview-features only.

Represents a whole or partial calendar date, such as a birthday. The time of day and time zone are either specified elsewhere or are insignificant. The date is relative to the Gregorian Calendar. This can represent one of the following:

• A full date, with non-zero year, month, and day values.
• A month and day, with a zero year (for example, an anniversary).
• A year on its own, with a zero month and a zero day.
• A year and month, with a zero day (for example, a credit card expiration date).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

day: Option<i32>

Day of a month. Must be from 1 to 31 and valid for the year and month, or 0 to specify a year by itself or a year and month where the day isn’t significant.

month: Option<i32>

Month of a year. Must be from 1 to 12, or 0 to specify a year without a month and day.

year: Option<i32>

Year of the date. Must be from 1 to 9999, or 0 to specify a date without a year.

Implementations

impl Date

pub fn new() -> Self

pub fn set_day<T>(self, v: T) -> Self

where T: Into<i32>,

Sets the value of day.

Example

let x = Date::new().set_day(42);

pub fn set_or_clear_day<T>(self, v: Option<T>) -> Self

where T: Into<i32>,

Sets or clears the value of day.

Example

let x = Date::new().set_or_clear_day(Some(42));
let x = Date::new().set_or_clear_day(None::<i32>);

pub fn set_month<T>(self, v: T) -> Self

where T: Into<i32>,

Sets the value of month.

Example

let x = Date::new().set_month(42);

pub fn set_or_clear_month<T>(self, v: Option<T>) -> Self

where T: Into<i32>,

Sets or clears the value of month.

Example

let x = Date::new().set_or_clear_month(Some(42));
let x = Date::new().set_or_clear_month(None::<i32>);

pub fn set_year<T>(self, v: T) -> Self

where T: Into<i32>,

Sets the value of year.

Example

let x = Date::new().set_year(42);

pub fn set_or_clear_year<T>(self, v: Option<T>) -> Self

where T: Into<i32>,

Sets or clears the value of year.

Example

let x = Date::new().set_or_clear_year(Some(42));
let x = Date::new().set_or_clear_year(None::<i32>);

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 Message for Date

fn typename() -> &'static str

The typename of this message.

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.
