}Expand description
Controls how unknown enum values are handled.
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.
Open
Unknown values are preserved in the field (first-class EnumValue<E>).
Closed
Unknown values are stored in unknown fields.
