Struct StoreLock 

pub struct StoreLock { /* private fields */ }

Exclusive writer lock represented by a restrictive sidecar file.

Implementations

impl StoreLock

pub fn acquire( database_path: &Path, stale_after: Duration, ) -> Result<Self, StoreError>

Acquires an exclusive writer lock and recovers an expired lock once.

The sidecar path is the database path with .lock appended to its extension. On Unix it is created with mode 0600. Dropping the returned guard removes only a lock whose token still matches this owner.

Errors

Returns StoreError::LockHeld for an active lock or StoreError::Io when lock metadata cannot be created, inspected, or replaced.
