Enum PropertyState 

#[non_exhaustive]
pub enum PropertyState {
    NewValue,
    Delete,
}

Specifies the type of a property change for a EventProperty.

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.

NewValue

the property value was changed.

Delete

the property was deleted.
