rotating-file

A thread-safe rotating file with customizable rotation behavior.

Example

use chrono::{DateTime, Utc};
use std::path::Path;
use std::time::SystemTime;
use rotating_file::RotatingFile;

fn main() {
    let root_dir = "./target/tmp";
    let s = "The quick brown fox jumps over the lazy dog";
    let rotating_file = RotatingFile::new(root_dir, Some(1), None, None, None, None, None);

    let dt: DateTime::<Utc> = SystemTime::now().into();
    let timestamp = dt.format("%Y-%m-%d-%H-%M-%S").to_string();
    for _ in 0..23 {
        rotating_file.writeln(s).unwrap();
    }

    rotating_file.close();

    assert!(Path::new(root_dir).join(timestamp.clone() + ".log").exists());
    assert!(!Path::new(root_dir).join(timestamp.clone() + "-1.log").exists());
    std::fs::remove_dir_all(root_dir).unwrap();
}
