Struct Collection 

pub struct Collection { /* private fields */ }

A handle to a named document collection inside a Database.

Provides MongoDB-compatible methods: insert_one, find_one, find, update_one, update_many, delete_one, delete_many, count_documents.

Implementations

impl Collection

pub fn name(&self) -> &str

The collection name.

pub fn insert_one(&self, document: Value) -> Result<InsertOneResult>

Insert a single document and return its assigned ID.

let coll = client.database().collection("users");
let result = coll.insert_one(json!({"name": "Alice", "age": 30})).unwrap();
println!("inserted: {}", result.inserted_id);

pub fn insert_many(&self, documents: Vec<Value>) -> Result<InsertManyResult>

Insert multiple documents and return all assigned IDs.

pub fn find_one(&self, filter: Option<&Value>) -> Result<Option<Value>>

Find a single document matching filter, or None if not found.

Supports {"_id": "..."} for fast lookup as well as arbitrary MongoDB-style operators.

pub fn find(&self, filter: Option<&Value>) -> Result<Cursor>

Return a Cursor over all documents that match filter.

Pass None to return every document in the collection.

pub fn update_one(&self, filter: &Value, update: &Value) -> Result<UpdateResult>

Update the first document that matches filter using update operators.

Supports $set, $unset, $inc, $push, and full replacement.

pub fn update_many( &self, filter: &Value, update: &Value, ) -> Result<UpdateResult>

Update all documents that match filter.

pub fn delete_one(&self, filter: &Value) -> Result<DeleteResult>

Delete the first document that matches filter.

pub fn delete_many(&self, filter: &Value) -> Result<DeleteResult>

Delete all documents that match filter.

pub fn count_documents(&self, filter: Option<&Value>) -> Result<usize>

Count documents matching filter, or all documents when None.
