Enum icu::datetime::fieldsets::enums::CompositeDateTimeFieldSet

#[non_exhaustive]
pub enum CompositeDateTimeFieldSet {
    Date(DateFieldSet),
    CalendarPeriod(CalendarPeriodFieldSet),
    Time(TimeFieldSet),
    DateTime(DateAndTimeFieldSet),
}

An enum supporting date, calendar period, time, and date+time field sets and options.

Time zones are not supported with this enum.

This enum is useful when formatting a type that does not contain a time zone or to avoid storing time zone data.

This is a dynamic field set. For more information, see enums.

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.

Date(DateFieldSet)

Field set for a date.

CalendarPeriod(CalendarPeriodFieldSet)

Field set for a calendar period.

Time(TimeFieldSet)

Field set for a time.

DateTime(DateAndTimeFieldSet)

Field set for a date and a time together.

Implementations

impl CompositeDateTimeFieldSet

pub fn try_from_composite_field_set( field_set: CompositeFieldSet, ) -> Option<CompositeDateTimeFieldSet>

If the CompositeFieldSet does not contain a time zone, returns the corresponding CompositeDateTimeFieldSet.

pub fn to_composite_field_set(self) -> CompositeFieldSet

Returns the CompositeFieldSet corresponding to this CompositeDateTimeFieldSet.

Trait Implementations

impl Clone for CompositeDateTimeFieldSet

fn clone(&self) -> CompositeDateTimeFieldSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DateTimeMarkers for CompositeDateTimeFieldSet

type D = DateFieldSet

Associated types for date formatting.

type T = TimeFieldSet

Associated types for time formatting.

type Z = ()

Associated types for time zone formatting.

impl Debug for CompositeDateTimeFieldSet

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

Formats the value using the given formatter.

impl GetField<CompositeFieldSet> for CompositeDateTimeFieldSet

fn get_field(&self) -> CompositeFieldSet

Returns the value of this trait’s field T.

impl PartialEq for CompositeDateTimeFieldSet

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