documentation

Reference documentation is available here.

Example

extern crate syslog;

use syslog::{Facility,Severity};

fn main() {
  match syslog::unix(Facility::LOG_USER) {
    Err(e)         => println!("impossible to connect to syslog: {:?}", e),
    Ok(writer) => {
      let r = writer.send_3164(Severity::LOG_ALERT, "hello world");
      if r.is_err() {
        println!("error sending the log {}", r.err().expect("got error"));
      }
    }
  }
}

The struct syslog::Logger implements Log from the log crate, so it can be used as backend for other logging systems.

There are 3 functions to create loggers:

  • the unix function sends to the local syslog through a Unix socket: syslog::unix(Facility::LOG_USER)
  • the tcp function takes an address for a remote TCP syslog server and a hostname: tcp("127.0.0.1:4242", "localhost".to_string(), Facility::LOG_USER)
  • the udp function takes an address for a local port, and the address remote UDP syslog server and a hostname: udp("127.0.0.1:1234", "127.0.0.1:4242", "localhost".to_string(), Facility::LOG_USER)
