Expand description

Fixed-format item types.

They have their own rules of formatting and parsing. Otherwise noted, they print in the specified cases but parse case-insensitively.

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.
§

ShortMonthName

Abbreviated month names.

Prints a three-letter-long name in the title case, reads the same name in any case.

§

LongMonthName

Full month names.

Prints a full name in the title case, reads either a short or full name in any case.

§

ShortWeekdayName

Abbreviated day of the week names.

Prints a three-letter-long name in the title case, reads the same name in any case.

§

LongWeekdayName

Full day of the week names.

Prints a full name in the title case, reads either a short or full name in any case.

§

LowerAmPm

AM/PM.

Prints in lower case, reads in any case.

§

UpperAmPm

AM/PM.

Prints in upper case, reads in any case.

§

Nanosecond

An optional dot plus one or more digits for left-aligned nanoseconds. May print nothing, 3, 6 or 9 digits according to the available accuracy. See also Numeric::Nanosecond.

§

Nanosecond3

Same as Nanosecond but the accuracy is fixed to 3.

§

Nanosecond6

Same as Nanosecond but the accuracy is fixed to 6.

§

Nanosecond9

Same as Nanosecond but the accuracy is fixed to 9.

§

TimezoneName

Timezone name.

It does not support parsing, its use in the parser is an immediate failure.

§

TimezoneOffsetColon

Offset from the local time to UTC (+09:00 or -04:00 or +00:00).

In the parser, the colon can be omitted and/or surrounded with any amount of whitespace. The offset is limited from -24:00 to +24:00, which is the same as FixedOffset’s range.

§

TimezoneOffsetDoubleColon

Offset from the local time to UTC with seconds (+09:00:00 or -04:00:00 or +00:00:00).

In the parser, the colon can be omitted and/or surrounded with any amount of whitespace. The offset is limited from -24:00:00 to +24:00:00, which is the same as FixedOffset’s range.

§

TimezoneOffsetTripleColon

Offset from the local time to UTC without minutes (+09 or -04 or +00).

In the parser, the colon can be omitted and/or surrounded with any amount of whitespace. The offset is limited from -24 to +24, which is the same as FixedOffset’s range.

§

TimezoneOffsetColonZ

Offset from the local time to UTC (+09:00 or -04:00 or Z).

In the parser, the colon can be omitted and/or surrounded with any amount of whitespace, and Z can be either in upper case or in lower case. The offset is limited from -24:00 to +24:00, which is the same as FixedOffset’s range.

§

TimezoneOffset

Same as TimezoneOffsetColon but prints no colon. Parsing allows an optional colon.

§

TimezoneOffsetZ

Same as TimezoneOffsetColonZ but prints no colon. Parsing allows an optional colon.

§

RFC2822

RFC 2822 date and time syntax. Commonly used for email and MIME date and time.

§

RFC3339

RFC 3339 & ISO 8601 date and time syntax.

§

Internal(InternalFixed)

Internal uses only.

This item exists so that one can add additional internal-only formatting without breaking major compatibility (as enum variants cannot be selectively private).
