The slot retrieving backend for a totally ordered sequence (i.e. a chain).

Required Methods

fn start_lyquid( &mut self, lyquid: &LyquidID, sequence: Sequence, store: Arc<dyn KVStore>, ) -> Result<Recipient<Stop>, Error>

Start an actor to work on fill slots for the given lyquid. The actor can be stopped by sending lyquor_api::actor::Stop.

fn stop<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Stop the backend.

Provided Methods

fn prune<'life0, 'async_trait>( &'life0 self, until: u64, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: Sync + 'async_trait, 'life0: 'async_trait,

Let the backend prune all its persisted data prior to the given block number (exclusive).
