Trait 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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
