pub struct StorageLock(/* private fields */);Expand description
A file lock for a storage directory to ensure exclusive read-write access across different processes.
This lock stores the PID of the process holding it and is released (deleted) on a graceful shutdown. On resuming from a crash, the stored PID helps verify that no other process holds the lock.
Implementations§
Source§impl StorageLock
impl StorageLock
Sourcepub fn try_acquire(path: &Path) -> Result<Self, StorageLockError>
pub fn try_acquire(path: &Path) -> Result<Self, StorageLockError>
Tries to acquire a write lock on the target directory, returning [StorageLockError] if
unsuccessful.
Note: In-process exclusivity is not on scope. If called from the same process (or another with the same PID), it will succeed.
