syslog-rs

An implementation of the syslog from glibc/libc like it was designed in in both system libraries. The API is almost compatible with what is in libc/glibc.

Available features:

• feature = "use_async" for asynchronious code
• feature = "use_sync" for synchronious code
• feature = "use_sync_queue" for synchronious with async processing

The use_sync is acting like the libc's/glibc's functions syslog(), openlog()...

The use_sync_queue has the same API as libc/glibc but is different in some ways. Also, it spawns a worker thread which sends messages from the queue to syslog.

The use_async is async realization of the use_sync. Untested, probably requires further dev.

All 3 features can be used simpltaniously.

Usage:

syslog-rs = {version = "0.1", default-features = false, features = ["use_sync"]}

Supports

• GNU/Linux RFC3164 (UTF-8 by default)
• *BSD and OSX RFC5424 (BOM UTF-8 by default)

Example

#[macro_use] extern crate lazy_static;
#[macro_use] extern crate syslog_rs;

use std::sync::Arc;
use std::thread;
use std::time::{Instant, Duration};

use syslog_rs::{Syslog, LogStat, LogFacility, Priority};


lazy_static! {
    static ref SYSLOG: Arc<Syslog> = 
        Arc::new(
            Syslog::openlog(
                Some("example"), 
                LogStat::LOG_CONS | LogStat::LOG_NDELAY | LogStat::LOG_PID, 
                LogFacility::LOG_DAEMON
            ).unwrap()
        );
}

macro_rules! logdebug 
{
    ($($arg:tt)*) => (
        SYSLOG.syslog(Priority::LOG_DEBUG, format!($($arg)*))
    )
}



fn main()
{
    logdebug!("test message!");

    thread::sleep(Duration::from_micros(10));

    return;
}

Benchmarking

The test spawns 2 threads and one main thread. All 3 threads are sending messages to syslog. The time measurment in the tables are approximations.
