Trait db_rs::compacter::BackgroundCompacter

pub trait BackgroundCompacter {
    // Required method
    fn begin_compacter(
        &self,
        freq: Duration,
        cancel: CancelSig
    ) -> JoinHandle<DbResult<usize>>;
}

Required Methods

fn begin_compacter( &self, freq: Duration, cancel: CancelSig ) -> JoinHandle<DbResult<usize>>

Periodically compact the database log in a separate thread You can call this function if your db is wrapped in an Arc<Mutex>

freq determines how often the background thread will aquire a mutex and call compact_log() on your db

cancel is an AtomicBool which can be passed in and signal that compaction should cease (could take up-to freq to return)

this fn returns the number of times compaction took place
