filelock-rs

filelock-rs is a Rust library that provides functionality for managing PID files and file locks.

Features

• Pid: The pid module provides functionality for creating, reading, and managing PID files.
• FdLock: The fdlock module provides a trait FdLock that extends the AsRawFd trait, allowing file locks to be placed on file descriptors.

Installation

Add this to your Cargo.toml:

[dependencies]
filelock-rs = "0.1.0"

Usage

use filelock-rs_rs::pid::Pid;
use filelock-rs_rs::fdlock::FdLock;

fn main() {
    // Store the file in the struct of the process
    // because the pid stop to exist when this Pid instance
    // is dropped.
    let pid_file = Pid::new("/var/run", "my_app").expect("Failed to create PID file");

    let file = std::fs::File::new("/tmp/file.txt").unwrap();
    // Lock the file exclusively
    file.lock_exclusive().expect("Failed to lock PID file");

    // Perform some operations...

    // Unlock the file
    file.unlock().expect("Failed to unlock PID file");
}
