Enum icu::datetime::neo_skeleton::NeoCalendarPeriodComponents

#[non_exhaustive]
pub enum NeoCalendarPeriodComponents {
    Month,
    YearMonth,
    Year,
}

A specification for a set of parts of a date. Only sets that yield “sensible” dates are allowed: this type cannot describe a date such as “August, Anno Domini”.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Month

A standalone month, as in “January”.

YearMonth

A month and year, as in “January 2000”.

Year

A year, as in “2000”.

Implementations

impl NeoCalendarPeriodComponents

pub const VALUES: &'static [NeoCalendarPeriodComponents] = _

All values of this enum.

pub const fn id_str(self) -> &'static DataMarkerAttributes

Returns a stable string identifying this set of components.

For details, see NeoDateComponents::id_str().

pub fn from_id_str( id_str: &DataMarkerAttributes, ) -> Option<NeoCalendarPeriodComponents>

Returns the set of components for the given stable string.

For details, see NeoDateComponents::from_id_str().

pub fn has_year(self) -> bool

Whether this field set contains the year.

pub fn has_month(self) -> bool

Whether this field set contains the month.

pub fn long(self) -> NeoCalendarPeriodSkeleton

Creates a skeleton for this field set with a long length.

pub fn medium(self) -> NeoCalendarPeriodSkeleton

Creates a skeleton for this field set with a medium length.

pub fn short(self) -> NeoCalendarPeriodSkeleton

Creates a skeleton for this field set with a short length.

Trait Implementations

impl Clone for NeoCalendarPeriodComponents

fn clone(&self) -> NeoCalendarPeriodComponents

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NeoCalendarPeriodComponents

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

Formats the value using the given formatter.

impl From<NeoCalendarPeriodComponents> for NeoComponents

fn from(value: NeoCalendarPeriodComponents) -> NeoComponents

Converts to this type from the input type.

impl From<NeoCalendarPeriodComponents> for NeoDateTimeComponents

fn from(value: NeoCalendarPeriodComponents) -> NeoDateTimeComponents

Converts to this type from the input type.

impl Hash for NeoCalendarPeriodComponents

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 PartialEq for NeoCalendarPeriodComponents

fn eq(&self, other: &NeoCalendarPeriodComponents) -> 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.
