Enum mongodb::options::FullDocumentBeforeChangeType

#[non_exhaustive]
pub enum FullDocumentBeforeChangeType {
    WhenAvailable,
    Required,
    Off,
    Other(String),
}

Describes the modes for configuring the ChangeStreamEvent::full_document_before_change field.

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.

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.
