Enum icu_datetime::options::YearStyle

#[non_exhaustive]
pub enum YearStyle {
    Auto,
    Full,
    Always,
}

A specification of how to render the year and the era.

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.

Auto

Display the century and/or era when needed to disambiguate the year, based on locale preferences.

This is the default option.

Examples:

• 1000 BC
• 77 AD
• 1900
• '24

Full

Always display the century, and display the era when needed to disambiguate the year, based on locale preferences.

Examples:

• 1000 BC
• 77 AD
• 1900
• 2024

Always

Always display the century and era.

Examples:

• 1000 BC
• 77 AD
• 1900 AD
• 2024 AD

Trait Implementations

impl Clone for YearStyle

fn clone(&self) -> YearStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for YearStyle

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for YearStyle

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
