}

An enum for the possible symbols of a time zone field in a date pattern.

Variants

LowerZ = 0

Field symbol for the specific non-location format of a time zone.

For example: “Pacific Standard Time”

This field symbol is represented by the character z in a date formatting pattern string.

For more details, see documentation on date field symbols.

UpperZ = 1

Field symbol for any of: the ISO8601 basic format with hours, minutes and optional seconds fields, the long localized GMT format, or the ISO8601 extended format with hours, minutes and optional seconds fields.

This field symbol is represented by the character Z in a date formatting pattern string.

For more details, see documentation on date field symbols.

UpperO = 2

Field symbol for the localized GMT format of a time zone.

For example: “GMT-07:00”

This field symbol is represented by the character O in a date formatting pattern string.

For more details, see documentation on date field symbols.

LowerV = 3

Field symbol for the generic non-location format of a time zone.

For example: “Pacific Time”

This field symbol is represented by the character v in a date formatting pattern string.

For more details, see documentation on date field symbols.

UpperV = 4

Field symbol for any of: the time zone id, time zone exemplar city, or generic location format.

This field symbol is represented by the character V in a date formatting pattern string.

For more details, see documentation on date field symbols.

LowerX = 5

Field symbol for either the ISO8601 basic format or ISO8601 extended format, with an optional ISO8601 UTC indicator Z.

This field symbol is represented by the character x in a date formatting pattern string.

For more details, see documentation on date field symbols.

UpperX = 6

Field symbol for either the ISO8601 basic format or ISO8601 extended format. This does not allow an optional ISO8601 UTC indicator Z, whereas TimeZone::LowerX allows the optional Z.

This field symbol is represented by the character X in a date formatting pattern string.

For more details, see documentation on date field symbols.

Implementations

impl TimeZone

pub(crate) fn new_from_u8(value: u8) -> Option<Self>

Attempt to construct the value from its corresponding integer, returning None if not possible

impl TimeZone

pub(crate) fn idx(self) -> u8

Retrieves an index of the field variant.

Examples

use icu::datetime::fields::Month;

assert_eq!(Month::StandAlone::idx(), 1);

Stability

This is mostly useful for serialization, and does not guarantee index stability between ICU4X versions.

pub(crate) fn from_idx(idx: u8) -> Result<Self, SymbolError>

Retrieves a field variant from an index.

Examples

use icu::datetime::fields::Month;

assert_eq!(Month::from_idx(0), Month::Format);

Stability

This is mostly useful for serialization, and does not guarantee index stability between ICU4X versions.

Trait Implementations

impl AsULE for TimeZone

type ULE = TimeZoneULE

The ULE type corresponding to Self.

fn to_unaligned(self) -> Self::ULE

Converts from Self to Self::ULE.

fn from_unaligned(other: Self::ULE) -> Self

Converts from Self::ULE to Self.

impl Clone for TimeZone

fn clone(&self) -> TimeZone

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TimeZone

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

Formats the value using the given formatter.

impl From<TimeZone> for FieldSymbol

fn from(input: TimeZone) -> Self

Converts to this type from the input type.

impl From<TimeZone> for char

fn from(input: TimeZone) -> char

Converts to this type from the input type.

impl Ord for TimeZone

fn cmp(&self, other: &TimeZone) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for TimeZone

fn eq(&self, other: &TimeZone) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TimeZone

fn partial_cmp(&self, other: &TimeZone) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<char> for TimeZone

type Error = SymbolError

The type returned in the event of a conversion error.

fn try_from(ch: char) -> Result<Self, Self::Error>

Performs the conversion.

impl<'a> Yokeable<'a> for TimeZone

where Self: Sized,

type Output = TimeZone

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&self) -> &Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.

fn zero_from(this: &'zf Self) -> Self

Clone the other C into a struct that may retain references into C.

impl<'a> ZeroMapKV<'a> for TimeZone

type Container = ZeroVec<'a, TimeZone>

type Slice = ZeroSlice<TimeZone>

type GetType = TimeZoneULE

The type produced by Container::get()

type OwnedType = TimeZone

The type produced by Container::replace() and Container::remove(), also used during deserialization. If Self is human readable serialized, deserializing to Self::OwnedType should produce the same value once passed through Self::owned_as_self()
