OperationGuard

meerkat_sqlite::fence

Struct OperationGuard 

Source 
pub struct OperationGuard { /* private fields */ }
Expand description

RAII shared guard for one store operation on one database file.

Held for the duration of the operation; dropping it releases the lock.

Implementations§

Source§

impl OperationGuard

Source

pub fn for_database(db_path: &Path) -> Result<Self, SqliteStoreError>

Acquire the shared guard for an operation on db_path.

Returns SqliteStoreError::MaintenanceFenceHeld when the exclusive maintenance fence is held. In-memory databases and media where no lock file can exist yield a no-op guard.
