Struct time::format_description::well_known::Iso8601

pub struct Iso8601<const CONFIG: EncodedConfig = DEFAULT_CONFIG>;

The format described in ISO 8601.

This implementation is of ISO 8601-1:2019. It may not be compatible with other versions.

The const parameter CONFIG must be a value that was returned by Config::encode. Passing any other value is unspecified behavior.

Example: 1997-11-21T09:55:06.000000000-06:00

Examples

assert_eq!(
    datetime!(1997-11-12 9:55:06 -6:00).format(&Iso8601::DEFAULT)?,
    "1997-11-12T09:55:06.000000000-06:00"
);

Implementations

impl Iso8601<DEFAULT_CONFIG>

pub const DEFAULT: Self = Self

An Iso8601 with the default configuration.

The following is the default behavior:

• The configuration can be used for both formatting and parsing.
• The date, time, and UTC offset are all formatted.
• Separators (such as - and :) are included.
• The year contains four digits, such that the year must be between 0 and 9999.
• The date uses the calendar format.
• The time has precision to the second and nine decimal digits.
• The UTC offset has precision to the minute.

If you need different behavior, use Config::DEFAULT and Config’s methods to create a custom configuration.

impl Iso8601<PARSING_ONLY>

pub const PARSING: Self = Self

An Iso8601 that can only be used for parsing. Using this to format a value is unspecified behavior.

Trait Implementations

impl<const CONFIG: EncodedConfig> Clone for Iso8601<CONFIG>

fn clone(&self) -> Iso8601<CONFIG>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<const CONFIG: EncodedConfig> Debug for Iso8601<CONFIG>

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

Formats the value using the given formatter.

impl<const CONFIG: EncodedConfig> PartialEq for Iso8601<CONFIG>

fn eq(&self, other: &Iso8601<CONFIG>) -> 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.
