Struct icu_datetime::provider::calendar::Eras

pub struct Eras<'data> {
    pub names: ZeroMap<'data, UnvalidatedStr, str>,
    pub abbr: ZeroMap<'data, UnvalidatedStr, str>,
    pub narrow: ZeroMap<'data, UnvalidatedStr, str>,
}

String data for the name, abbreviation, and narrow form of a date’s era.

Keys of the map represent era codes, and the values are the display names.

Era codes are derived from CLDR data, and are calendar specific. Some examples include: "be", "0" / "1", "bce" / "ce", "heisei" / "meiji" / "reiwa" / … Not all era codes are inherited as-is, such as for the extended Japanese calendar.

For more information on date time symbols, see FieldSymbol.

🚧 This code is considered unstable; it may change at any time, in breaking or non-breaking ways, including in SemVer minor releases. While the serde representation of data structs is guaranteed to be stable, their Rust representation might not be. Use with caution.

Fields

names: ZeroMap<'data, UnvalidatedStr, str>

Keys are era codes, and values are display names. See Eras.

abbr: ZeroMap<'data, UnvalidatedStr, str>

Symbol data for era abbreviations.

Keys are era codes, and values are display names. See Eras.

narrow: ZeroMap<'data, UnvalidatedStr, str>

Symbol data for era narrow forms.

Keys are era codes, and values are display names. See Eras.

Trait Implementations

impl<'data> Clone for Eras<'data>

fn clone(&self) -> Eras<'data>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'data> Debug for Eras<'data>

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

Formats the value using the given formatter.

impl<'data> Default for Eras<'data>

fn default() -> Eras<'data>

Returns the “default value” for a type.

impl<'data> PartialEq for Eras<'data>

fn eq(&self, other: &Eras<'data>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a> Yokeable<'a> for Eras<'static>

type Output = Eras<'a>

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

fn transform(&'a self) -> &'a Self::Output

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

fn transform_owned(self) -> Self::Output

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

unsafe fn make(this: Self::Output) -> Self

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 Self::Output),

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

impl<'zf, 'zf_inner> ZeroFrom<'zf, Eras<'zf_inner>> for Eras<'zf>

fn zero_from(this: &'zf Eras<'zf_inner>) -> Self

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