Struct Date 

pub struct Date {
    pub year: u16,
    pub month: u8,
    pub day: u8,
}

A calendar date, for expires:.

Deliberately not a general date type: it exists to be parsed from YYYY-MM-DD, compared, and printed. Comparison is on the tuple, which is why the fields are in that order.

Fields

year: u16

Four-digit year.

month: u8

One-based month.

day: u8

One-based day.

Implementations

impl Date

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

Parse YYYY-MM-DD.

Rejects anything else, including a real date written another way. A directive whose expiry could not be read would otherwise never expire, which is the one outcome an expiry exists to prevent.

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 Copy for Date

impl Eq for Date

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

Equality operator ==.

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

Inequality operator !=.

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.
