Struct time::format_description::well_known::Iso8601

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

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§

source§

impl Iso8601<DEFAULT>

source

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.

source§

impl Iso8601<PARSING>

source

pub const PARSING: Self = Self

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

source§

impl Iso8601<DATE>

source

pub const DATE: Self = Self

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

source§

impl Iso8601<TIME>

source

pub const TIME: Self = Self

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

source§

impl Iso8601<OFFSET>

source

pub const OFFSET: Self = Self

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

source§

impl Iso8601<DATE_TIME>

source

pub const DATE_TIME: Self = Self

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

source§

impl Iso8601<DATE_TIME_OFFSET>

source

pub const DATE_TIME_OFFSET: Self = Self

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

source§

impl Iso8601<TIME_OFFSET>

source

pub const TIME_OFFSET: Self = Self

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