#[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”.
