I am just trying to establish a connection with MongoDB Atlas in Rust for learning purposes

Here is what I am getting

thread 'tokio-runtime-worker' panicked at srcdb_connection.rs:33:14:
error connecting to database: Error { kind: InvalidArgument { message: "connection string contains no scheme" }, labels: {}, wire_version: None, source: None }
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Here is the Code I am using

dotenv().ok();
        let uri = match env::var("MONGOURI") {
            Ok(v) => v.to_string(),
            Err(_) => format!("Error loading env variable"),
        };
        let client = Client::with_uri_str(uri)
            .await
            .expect("error connecting to database");
        let col = client.database("mydb").collection("mycol");

Here is what I am using in .env

MONGOURI=mongodb+srv://username:[email protected]/mydb?retryWrites=true&w=majority

Please let me know, where I’m doing mistake
