Struct conserve::GarbageCollectionLock

impl GarbageCollectionLock

Lock on an archive for gc, that excludes backups and gc by other processes.

The lock is released when the object is dropped.

pub fn new(archive: &Archive) -> Result<GarbageCollectionLock>

Lock this archive for garbage collection.

Returns Err(Error::DeleteWithIncompleteBackup) if the last backup is incomplete.

pub fn break_lock(archive: &Archive) -> Result<GarbageCollectionLock>

Take a lock on an archive, breaking any existing gc lock.

Use this only if you’re confident that the process owning the lock has terminated and the lock is stale.

pub fn is_locked(archive: &Archive) -> Result<bool>

Returns true if the archive is currently locked by a gc process.

pub fn check(&self) -> Result<()>

Check that no new versions have been created in this archive since the guard was created.
