Enum parse_zoneinfo::line::DaySpec

pub enum DaySpec {
    Ordinal(i8),
    Last(Weekday),
    LastOnOrBefore(Weekday, i8),
    FirstOnOrAfter(Weekday, i8),
}

A day definition field.

This can be given in either absolute terms (such as “the fifth day of the month”), or relative terms (such as “the last Sunday of the month”, or “the last Friday before or including the 13th”).

Note that in the last example, it’s allowed for that particular Friday to be the 13th in question.

Variants

Ordinal(i8)

A specific day of the month, given by its number.

Last(Weekday)

The last day of the month with a specific weekday.

LastOnOrBefore(Weekday, i8)

The last day with the given weekday before (or including) a day with a specific number.

FirstOnOrAfter(Weekday, i8)

The first day with the given weekday after (or including) a day with a specific number.

Implementations

impl DaySpec

pub fn to_concrete_day(&self, year: i64, month: Month) -> (Month, i8)

Converts this day specification to a concrete date, given the year and month it should occur in.

Trait Implementations

impl Clone for DaySpec

fn clone(&self) -> DaySpec

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DaySpec

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

Formats the value using the given formatter.

impl PartialEq for DaySpec

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