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.

Fields

column: String

ElementKey

Map key or list index of an element update, delete or restriction.

Fields

column: String

The collection column.

ElementValue
