Welcome to the documentation site for the official MongoDB Rust driver. You can add the driver to your application to work with MongoDB in Rust. Download it from or set up a runnable project with examples from our Usage Guide.

See Installation

Select from the Sync or Async tabs below for corresponding connection code samples.

To connect to a MongoDB Atlas cluster, use the Atlas connection string for your cluster:


For information about connecting to Atlas Serverless, see the Serverless Instance Limitations page for the minimum driver version you need.

If you need to run a MongoDB server on your local machine for development purposes instead of using an Atlas cluster, you need to complete the following:

  1. Download the Community or Enterprise version of MongoDB Server.

  2. Install and configure MongoDB Server.

  3. Start the server.


Always secure your MongoDB server from malicious attacks. See our Security Checklist for a list of security recommendations.

After you successfully start your MongoDB server, specify your connection string in your driver connection code.

If your MongoDB Server is running locally, you can use the connection string "mongodb://localhost:<port>" where <port> is the port number you configured your server to listen for incoming connections.

If you need to specify a different hostname or IP address, see our Server Manual entry on Connection Strings.

To test whether you can connect to your server, replace the connection string in the Connect to MongoDB Atlas code example and run it.

All features are supported.
The Driver version will work with the MongoDB version, but not all new MongoDB features are supported.
No mark
The Driver version is not tested with the MongoDB version.

The Rust driver is not compatible with MongoDB server versions older than 3.6.

[1](1, 2) The Rust driver does not support Decimal128, Client-Side Field Level Encryption, GridFS, and OCSP.
[2] The Rust driver does not support Decimal128, Client-Side Field Level Encryption, GridFS, OCSP, and change streams.
[3] Not all features in MongoDB are available in these driver versions. Unsupported features include Decimal128, Client-Side Field Level Encryption, GridFS, OCSP, change streams, Causal Consistency, and Serverless Instances.
