The MongoDB Driver for Rust is an open-source driver that allows developers to interact with MongoDB databases using the Rust programming language. The driver is implemented in native Rust code, without relying on C extensions or libraries, and features a familiar API similar to other MongoDB drivers. It supports CRUD operations, indexing, and administrative functionality, while providing a balance between Rust's static guarantees and MongoDB's flexibility. The driver is currently available for Rust 0.7 and later versions, and its source code and documentation are available on GitHub.
