ProjectLock

chkpt_core::ops::lock

Struct ProjectLock

pub struct ProjectLock { /* private fields */ }

Expand description

A file-based project lock that provides mutual exclusion for save/restore/delete operations.

The lock is held by keeping an exclusive flock on a project.lock file. When the ProjectLock is dropped, the file is closed and the lock is automatically released.

Implementations§

impl ProjectLock

pub fn acquire(lock_dir: &Path) -> Result<ProjectLock>

Acquire an exclusive project lock.

Creates (or opens) lock_dir/project.lock and attempts to take an exclusive lock on it. Returns ChkpttError::LockHeld if another process already holds the lock.
