The Actix framework provides an actors model for Rust, based on the futures crate and some asynchronous code to allow actors to work concurrently with minimal resources needed.

I think this is one of the best tools for creating web applications and microservices with Rust. The framework includes two good crates—the actix crate that contains core structures, and the actix-web crate that implements the HTTP and WebSocket protocols. Let's create a microservice that routes requests to other microservices.
