Enum icu::datetime::neo_skeleton::NeoTimeZoneStyle

#[non_exhaustive]
pub enum NeoTimeZoneStyle {
    Default,
    Location,
    Generic,
    Specific,
    Offset,
}

Specification of the time zone display style.

Time zone names contribute a lot of data size. For resource-constrained environments, the following formats require the least amount of data:

• NeoTimeZoneStyle::Specific + NeoSkeletonLength::Short
• NeoTimeZoneStyle::Offset

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Default

The location format, e.g., “Los Angeles time” or specific non-location format “Pacific Daylight Time”, whichever is idiomatic for the locale.

Note: for now, this is always identical to NeoTimeZoneStyle::Specific (Pacific Daylight Time), but whether it is NeoTimeZoneStyle::Generic or NeoTimeZoneStyle::Specific will be locale-dependent in the future; see CLDR-15566.

Location

The location format, e.g., “Los Angeles time”.

When unavailable, falls back to NeoTimeZoneStyle::Offset.

Generic

The generic non-location format, e.g., “Pacific Time”.

When unavailable, falls back to NeoTimeZoneStyle::Location.

Specific

The specific non-location format, e.g., “Pacific Daylight Time”.

When unavailable, falls back to NeoTimeZoneStyle::Offset.

Offset

The offset format, e.g., “GMT−8”.

Implementations

impl NeoTimeZoneStyle

pub fn long(self) -> NeoTimeZoneSkeleton

Creates a skeleton for this time zone style with a long length.

pub fn medium(self) -> NeoTimeZoneSkeleton

Creates a skeleton for this time zone style with a medium length.

pub fn short(self) -> NeoTimeZoneSkeleton

Creates a skeleton for this time zone style with a short length.

Trait Implementations

impl Clone for NeoTimeZoneStyle

fn clone(&self) -> NeoTimeZoneStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NeoTimeZoneStyle

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

Formats the value using the given formatter.

impl Default for NeoTimeZoneStyle

fn default() -> NeoTimeZoneStyle

Returns the “default value” for a type.

impl From<NeoTimeZoneStyle> for NeoComponents

fn from(value: NeoTimeZoneStyle) -> NeoComponents

Converts to this type from the input type.

impl Hash for NeoTimeZoneStyle

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

where __H: Hasher,

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 NeoTimeZoneStyle

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