Struct Lock 

pub struct Lock {
    _file: File,
    path: PathBuf,
}

An exclusive advisory lock released when dropped or when the process exits.

The lock file remains on disk. Acquisition therefore cannot race with deletion and inode replacement.

Fields

_file: File

path: PathBuf

Implementations

impl Lock

pub fn try_acquire(path: &Path) -> Result<Self, LockError>

Attempt to acquire an exclusive advisory lock without waiting.

The lock is tied to the open file handle. A crashed process releases the operating-system lock automatically. Timestamp-based stale-lock recovery is neither required nor safe.

Errors

Returns LockError::is_busy when another process owns the lock. Opening and locking failures are returned with path context.

pub fn path(&self) -> &Path

Return the persistent lock-file path.

Trait Implementations

impl Debug for Lock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
