file-locker

File locking via POSIX advisory record locks (fork of file-lock)

This crate provides the facility to lock and unlock a file following the advisory record lock scheme as specified by UNIX IEEE Std 1003.1-2001 (POSIX.1) via fcntl().

This crate currently supports Linux and FreeBSD.

USAGE

use file_lock::FileLock;
use std::io::prelude::*;
use std::io::Result;

fn main() -> Result<()> {
    let filelock = FileLock::new("myfile.txt")
                    .writeable(true)
                    .blocking(true)
                    .lock()?;

    filelock.file.write_all(b"Hello, World!")?;

    // Manually unlocking is optional as we unlock on Drop
    filelock.unlock();
}
