Provided Methods

fn try_get_log_entry( &mut self, log_index: u64 ) -> impl Future<Output = Result<Option<C::Entry>, StorageError<C::NodeId>>> + Send

Try to get an log entry.

It does not return an error if the log entry at log_index is not found.

fn get_log_entries<RB: RangeBounds<u64> + Clone + Debug + OptionalSend + OptionalSync>( &mut self, range: RB ) -> impl Future<Output = Result<Vec<C::Entry>, StorageError<C::NodeId>>> + Send

Get a series of log entries from storage.

Similar to try_get_log_entries except an error will be returned if there is an entry not found in the specified range.

fn get_log_id( &mut self, log_index: u64 ) -> impl Future<Output = Result<LogId<C::NodeId>, StorageError<C::NodeId>>> + Send

Get the log id of the entry at index.
