Enum icu::datetime::fieldset::dynamic::ZoneFieldSet

source ·
#[non_exhaustive]
pub enum ZoneFieldSet { Z(Z), O(O), V(V), L(L), }
Expand description

An enumeration over all possible zone field sets.

📏 Note: This enum can be used as the field set parameter of DateTimeFormatter, but doing so may link more formatting data compared to the individual field set structs.

Note: fieldset::Zs and fieldset::Vs are not included in this enum because they are data size optimizations only.

§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:

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Z(Z)

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

§

O(O)

The offset format, as in “GMT−8”.

§

V(V)

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

§

L(L)

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