}
Expand description
Describes the modes for configuring the
ChangeStreamEvent::full_document_before_change
field.
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.
WhenAvailable
The field will be populated for replace, update, and delete change events if the pre-image for this event is available.
Required
The same behavior as WhenAvailable
except that an error is raised if the pre-image is
not available.
Off
Do not send a value.
Other(String)
User-defined other types for forward compatibility.
