Variants (Non-exhaustive)§

This enum is marked as 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.
§

Day(Day)

Day of the month.

§

Month(Month)

Month of the year.

§

Ordinal(Ordinal)

Ordinal day of the year.

§

Weekday(Weekday)

Day of the week.

§

WeekNumber(WeekNumber)

Week within the year.

§

Year(Year)

Year of the date.

§

Hour(Hour)

Hour of the day.

§

Minute(Minute)

Minute within the hour.

§

Period(Period)

AM/PM part of the time.

§

Second(Second)

Second within the minute.

§

Subsecond(Subsecond)

Subsecond within the second.

§

OffsetHour(OffsetHour)

Hour of the UTC offset.

§

OffsetMinute(OffsetMinute)

Minute within the hour of the UTC offset.

§

OffsetSecond(OffsetSecond)

Second within the minute of the UTC offset.

§

Ignore(Ignore)

A number of bytes to ignore when parsing. This has no effect on formatting.

§

UnixTimestamp(UnixTimestamp)

A Unix timestamp.

§

End(End)

The end of input. Parsing this component will fail if there is any input remaining. This component neither affects formatting nor consumes any input when parsing.
