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

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).

Trait Implementations

impl Clone for Fixed

fn clone(&self) -> Fixed

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Fixed

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

Formats the value using the given formatter.

impl Hash for Fixed

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Fixed

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

impl Eq for Fixed

impl StructuralPartialEq for Fixed
