Installation

$ cargo add filelock

Usage

use filelock;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut lock = filelock::new("myfile.lock");
    let _guard = lock.lock()?;

    // Perform critical operations

    // Lock is automatically released when _guard goes out of scope
    Ok(())
}

For manual control:

use filelock;

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut lock = filelock::new("myfile.lock");
    let guard = lock.lock()?;

    // Perform critical operations

    // Manually unlock with error handling
    guard.unlock()?;

    Ok(())
}
