Hands-On Microservices with Rust

Using logging

We can now add logging to our microservice. In the following example, we will print information about the socket address, the incoming request, and a generated random value:

fn main() {     logger::init();     info!("Rand Microservice - v0.1.0");     trace!("Starting...");     let addr = ([127, 0, 0, 1], 8080).into();     debug!("Trying to bind server to address: {}", addr);     let builder = Server::bind(&addr);     trace!("Creating service handler...");     let server = builder.serve(|| {         service_fn_ok(|req| {             trace!("Incoming request is: {:?}", req);             let random_byte = rand::random::<u8>();             debug!("Generated value is: {}", random_byte);             Response::new(Body::from(random_byte.to_string()))         })     });     info!("Used address: {}", server.local_addr()); let server = ...
