FileLockGuard

Struct FileLockGuard 

Source
pub struct FileLockGuard<'a> { /* private fields */ }
Expand description

A guard that holds a file lock and automatically releases it when dropped.

This guard is returned by FileLock::lock() and ensures that the lock is properly released when it goes out of scope.

Implementations§

Source§

impl<'a> FileLockGuard<'a>

Source

pub fn new(lock: &'a mut FileLock) -> Self

Source

pub fn unlock(self) -> Result<(), Errno>

Manually unlocks the file lock.

This method consumes the guard and returns a result indicating whether the unlock operation was successful.

§Examples
use filelock::FileLock;

let mut lock = FileLock::new("myfile.lock");
let guard = lock.lock().unwrap();

// Perform critical operations

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