Struct Year

source
#[non_exhaustive]
pub struct Year { pub padding: Padding, pub repr: YearRepr, pub iso_week_based: bool, pub sign_is_mandatory: bool, }
Expand description

Year of the date.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§padding: Padding

The padding to obtain the minimum width.

§repr: YearRepr

What kind of representation should be used?

§iso_week_based: bool

Whether the value is based on the ISO week number or the Gregorian calendar.

§sign_is_mandatory: bool

Whether the + sign is present when a positive year contains fewer than five digits.

Implementations§

source§

impl Year

source

pub const fn default() -> Self

Creates a modifier that indicates the value uses the Full representation, is padded with zeroes, uses the Gregorian calendar as its base, and only includes the year’s sign if necessary.

This function exists since Default::default() cannot be used in a const context. It may be removed once that becomes possible. As the Default trait is in the prelude, removing this function in the future will not cause any resolution failures for the overwhelming majority of users; only users who use #![no_implicit_prelude] will be affected. As such it will not be considered a breaking change.
