Struct UpdateResult 

#[non_exhaustive]
pub struct UpdateResult {
    pub matched_count: i64,
    pub modified_count: i64,
    pub upserted_id: Option<Bson>,
}

The result of a Collection::update_one or Collection::update_many operation.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

matched_count: i64

The number of documents that matched the filter.

modified_count: i64

The number of documents that were modified by the operation.

upserted_id: Option<Bson>

The _id field of the upserted document.
