Enum icu::datetime::fields::Year

#[repr(u8)]
pub enum Year {
    Calendar,
    WeekOf,
}

An enum for the possible symbols of a year field in a date pattern.

Variants

Calendar

Field symbol for calendar year (numeric).

In most cases the length of this field specifies the minimum number of digits to display, zero-padded as necessary. For most use cases, Year::Calendar or Year::WeekOf should be adequate.

This field symbol is represented by the character y in a date formatting pattern string.

For more details, see documentation on date field symbols.

WeekOf

Field symbol for year in “week of year”.

This works for “week of year” based calendars in which the year transition occurs on a week boundary; may differ from calendar year Year::Calendar near a year transition. This numeric year designation is used in conjunction with Week::WeekOfYear, but can be used in non-Gregorian based calendar systems where week date processing is desired. The field length is interpreted in the same way as for Year::Calendar.

This field symbol is represented by the character Y in a date formatting pattern string.

For more details, see documentation on date field symbols.

) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl TryFrom<char> for Year

type Error = SymbolError

fn try_from(ch: char) -> Result<Year, <Year as TryFrom<char>>::Error>

Performs the conversion.

impl<'a> Yokeable<'a> for Year

type Output = Year

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&self) -> &<Year as Yokeable<'a>>::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> <Year as Yokeable<'a>>::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: <Year as Yokeable<'a>>::Output) -> Year

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F) where
    F: 'static + for<'b> FnOnce(&'b mut <Year as Yokeable<'a>>::Output), 

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

fn zero_from(this: &'zf Year) -> Year

Clone the other C into a struct that may retain references into C.

impl<'a> ZeroMapKV<'a> for Year

type Container = ZeroVec<'a, Year>

The container that can be used with this type: ZeroVec or VarZeroVec.

type Slice = ZeroSlice<Year>

type GetType = YearULE

The type produced by Container::get()

type OwnedType = Year

The type produced by Container::replace() and Container::remove(), also used during deserialization. If Self is human readable serialized, deserializing to Self::OwnedType should produce the same value once passed through Self::owned_as_self()
