Enum mongodb::options::FullDocumentType

#[non_exhaustive]
pub enum FullDocumentType {
    UpdateLookup,
    WhenAvailable,
    Required,
    Other(String),
}

Describes the modes for configuring the ChangeStreamEvent::full_document 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.

UpdateLookup

The field will be populated with a copy of the entire document that was updated.

WhenAvailable

The field will be populated for replace and update change events if the post-image for this event is available.

Required

The same behavior as WhenAvailable except that an error is raised if the post-image is not available.

Other(String)

User-defined other types for forward compatibility.
