Rust Log util

A log tool written in Rust that can work in conjunction with the log component of the standard library. It features synchronized log file recording and log file rolling capabilities.

Quick start

#[cfg(test)]
mod tests {
    use lazy_static::lazy_static;
    use log::{debug, error, info, warn};
    use log_util::LogUtil;

    use super::*;

    lazy_static! {
        static ref BASE_LOG: LogUtil = LogUtil::new("TestLog");
    }

    #[test]
    fn test_log() {
        LogUtil::init_with_logger(&BASE_LOG).unwrap();

        info!("Test");
        error!("Test: {}", 5);
        warn!("Test: {}", "abc");
        let b = "def";
        debug!("Test: {}, {b}", "abc");
    }
}

Run this test, you will see console print:

Debug Log display only when Set environment variable RUST_LOG="debug"
And you will got log/TestLog with 2 log files: TestLog.log, TestLog_xxxxxxxx.log

No global instance LogUtil(No log file out)

If you don't want to use LogUtil with a global variable instance, init LogUtil with:

LogUtil::init().unwrap()

Log messages will only print to console, no log file output.
