Struct time::format_description::well_known::iso8601::Iso8601

pub struct Iso8601<const CONFIG: EncodedConfig = { Config::DEFAULT.encode() }>;

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>

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 another associated constant. For full customization, use Config::DEFAULT and Config’s methods to create a custom configuration.

impl Iso8601<PARSING>

pub const PARSING: Self = Self

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

impl Iso8601<DATE>

pub const DATE: Self = Self

An Iso8601 that handles only the date, but is otherwise the same as Config::DEFAULT.

impl Iso8601<TIME>

pub const TIME: Self = Self

An Iso8601 that handles only the time, but is otherwise the same as Config::DEFAULT.

impl Iso8601<OFFSET>

pub const OFFSET: Self = Self

An Iso8601 that handles only the UTC offset, but is otherwise the same as Config::DEFAULT.

impl Iso8601<DATE_TIME>

pub const DATE_TIME: Self = Self

An Iso8601 that handles the date and time, but is otherwise the same as Config::DEFAULT.

impl Iso8601<DATE_TIME_OFFSET>

pub const DATE_TIME_OFFSET: Self = Self

An Iso8601 that handles the date, time, and UTC offset. This is the same as Config::DEFAULT.

impl Iso8601<TIME_OFFSET>

pub const TIME_OFFSET: Self = Self

An Iso8601 that handles the time and UTC offset, but is otherwise the same as Config::DEFAULT.

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<Iso8601<CONFIG>> 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.
