Hands-On Microservices with Rust

Actor

The main type is the LogActor struct, which contains a Logger instance in the writer field:

pub struct LogActor {    writer: Logger<LoggerBackend, String, Formatter3164>,}

We'll use this logger in the Handler trait implementation to write messages, but now we need a constructor for our struct, because we have to configure Logger on start:

impl LogActor {     pub fn new() -> Self {         let formatter = Formatter3164 {             facility: Facility::LOG_USER,             hostname: None,             process: "rust-microservice".into(),             pid: 0,         };         let writer = syslog::unix(formatter).unwrap();         Self {             writer,         }     } }

We added new method that fills the Formatter3164 struct with the Facility value and process name. Other fields are set to blank values. We create a Logger instance by calling ...
