$ cargo add filelockuse 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(())
