Struct icu::datetime::provider::calendar::Eras

pub struct Eras<'data> {
    pub names: ZeroMap<'data, PotentialUtf8, str>,
    pub abbr: ZeroMap<'data, PotentialUtf8, str>,
    pub narrow: ZeroMap<'data, PotentialUtf8, 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.

Trait Implementations

impl<'data> Bake for Eras<'data>

fn bake(&self, env: &CrateEnv) -> TokenStream

Returns a TokenStream that would evaluate to self.

impl<'data> BakeSize for Eras<'data>

fn borrows_size(&self) -> usize

Returns the size

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<(), Error>

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<'de, 'data> Deserialize<'de> for Eras<'data>

where 'de: 'data,

fn deserialize<__D>( __deserializer: __D, ) -> Result<Eras<'data>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

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

impl<'data> Serialize for Eras<'data>

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

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 <Eras<'static> as Yokeable<'a>>::Output

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

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

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

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

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 <Eras<'static> as Yokeable<'a>>::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>) -> Eras<'zf>

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

impl<'data> StructuralPartialEq for Eras<'data>
