Enum ZoneFieldSet

#[non_exhaustive]
pub enum ZoneFieldSet {
    SpecificLong(SpecificLong),
    SpecificShort(SpecificShort),
    LocalizedOffsetLong(LocalizedOffsetLong),
    LocalizedOffsetShort(LocalizedOffsetShort),
    GenericLong(GenericLong),
    GenericShort(GenericShort),
    Location(Location),
    ExemplarCity(ExemplarCity),
}

An enumeration over all possible zone field sets.

This is a dynamic field set. For more information, see enums.

Time Zone Data Size

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

• fieldsets::zone::SpecificShort
• fieldsets::zone::LocalizedOffsetLong

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.

SpecificLong(SpecificLong)

The long specific non-location format, as in “Pacific Daylight Time”.

SpecificShort(SpecificShort)

The short specific non-location format, as in “PDT”.

LocalizedOffsetLong(LocalizedOffsetLong)

The long offset format, as in “GMT−8:00”.

LocalizedOffsetShort(LocalizedOffsetShort)

The short offset format, as in “GMT−8”.

GenericLong(GenericLong)

The long generic non-location format, as in “Pacific Time”.

GenericShort(GenericShort)

The short generic non-location format, as in “PT”.

Location(Location)

The location format, as in “Los Angeles Time”.

ExemplarCity(ExemplarCity)

The exemplar city format, as in “Los Angeles.

impl GetField<CompositeFieldSet> for ZoneFieldSet

fn get_field(&self) -> CompositeFieldSet

Returns the value of this trait’s field T.

impl PartialEq for ZoneFieldSet

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