Enum mongodb::options::ReturnDocument

source · 
#[non_exhaustive]
pub enum ReturnDocument {
    After,
    Before,
}
Expand description

Specifies whether a Collection::find_one_and_replace and Collection::find_one_and_update operation should return the document before or after modification.

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.
§

After

Return the document after modification.

§

Before

Return the document before modification.
