Enum YearRange

#[non_exhaustive]
pub enum YearRange {
    Standard,
    Extended,
}

Available on crate features formatting or parsing only.

The range of years that are supported.

This modifier has no effect when the year repr is LastTwo.

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.

Standard

Years between -9999 and 9999 are supported.

Extended

Years between -999_999 and 999_999 are supported, with the sign being required if the year contains more than four digits.

If the large-dates feature is not enabled, this variant is equivalent to Standard.

Implementations

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

Performs copy-assignment from source.

impl Debug for YearRange

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

Formats the value using the given formatter.

impl Default for YearRange

Creates a modifier that indicates the value uses the Extended range.

fn default() -> Self

Returns the “default value” for a type.

impl Eq for YearRange

#[doc(hidden)] fn assert_receiver_is_total_eq(&self)

impl From<YearRange> for YearRange

Available on crate feature alloc only.

fn from(modifier: YearRange) -> Self

Converts to this type from the input type.

impl PartialEq for YearRange

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