Enum icu::calendar::types::FormattingEra

#[non_exhaustive]
pub enum FormattingEra {
    Index(u8, TinyAsciiStr<16>),
    Code(Era),
}

Information about the era as usable for formatting

This is optimized for storing datetime formatting data.

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.

Index(u8, TinyAsciiStr<16>)

An Era Index, for calendars with a small, fixed set of eras. The eras are indexed chronologically.

In this context, chronological ordering of eras is obtained by ordering by their start date (or in the case of negative eras, their end date) first, and for eras sharing a date, put the negative one first. For example, bce < ce, and mundi < pre-incar < incar for Ethiopian.

The TInyStr16 is a fallback string for the era when a display name is not available. It need not be an era code, it should be something sensible (or empty).

Code(Era)

An era code, for calendars with a large set of era codes (Japanese)

This code may not be the canonical era code, but will typically be a valid era alias

Implementations

impl FormattingEra

pub fn fallback_name(self) -> TinyAsciiStr<16>

Get a fallback era name suitable for display to the user when the real era name is not availabe

Trait Implementations

impl Clone for FormattingEra

fn clone(&self) -> FormattingEra

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FormattingEra

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

Formats the value using the given formatter.

impl PartialEq for FormattingEra

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