Required Methods§

Source

fn name(&self) -> &str

Source

fn count_documents(&self) -> Result<u64>

Return the size of all data in the collection.

Source

fn update_one(&self, query: Document, update: Document) -> Result<UpdateResult>

Updates up to one document matching query in the collection. documentation for more information on specifying updates.

Source

fn update_one_with_options( &self, query: Document, update: Document, options: UpdateOptions, ) -> Result<UpdateResult>

Source

fn update_many(&self, query: Document, update: Document) -> Result<UpdateResult>

Updates all documents matching query in the collection. documentation for more information on specifying updates.

Source

fn update_many_with_options( &self, query: Document, update: Document, options: UpdateOptions, ) -> Result<UpdateResult>

Source

fn delete_one(&self, query: Document) -> Result<DeleteResult>

Deletes up to one document found matching query.

Source

fn delete_many(&self, query: Document) -> Result<DeleteResult>

When query is None, all the data in the collection will be deleted.

The size of data deleted returns.

Source

fn create_index(&self, index: IndexModel) -> Result<()>

Source

fn drop_index(&self, name: impl AsRef<str>) -> Result<()>

Drops the index specified by name from this collection.

Source

fn drop(&self) -> Result<()>

Source

fn insert_one(&self, doc: impl Borrow<T>) -> Result<InsertOneResult>
where T: Serialize,

Inserts doc into the collection.

Source

fn insert_many( &self, docs: impl IntoIterator<Item = impl Borrow<T>>, ) -> Result<InsertManyResult>
where T: Serialize,

Inserts the data in docs into the collection.

Source

fn find(&self, filter: Document) -> Find<'_, '_, T>
where T: DeserializeOwned + Send + Sync,

When query document is passed to the function. The result satisfies the query document.

Source

fn find_one(&self, filter: Document) -> Result<Option<T>>
where T: DeserializeOwned + Send + Sync,

Finds a single document in the collection matching filter.

Source

fn aggregate( &self, pipeline: impl IntoIterator<Item = Document>, ) -> Aggregate<'_, '_>

Runs an aggregation operation.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
