Trait Implementations

impl RaftLogReader<AstraTypeConfig> for AstraLogStore

async fn try_get_log_entries<RB: RangeBounds<u64> + Clone + Debug + OptionalSend>( &mut self, range: RB, ) -> Result<Vec<Entry<AstraTypeConfig>>, StorageError<u64>>

Get a series of log entries from storage.

fn limited_get_log_entries( &mut self, start: u64, end: u64, ) -> impl Future<Output = Result<Vec<<C as RaftTypeConfig>::Entry>, StorageError<<C as RaftTypeConfig>::NodeId>>> + Send

Returns log entries within range [start, end), end is exclusive, potentially limited by implementation-defined constraints.

impl RaftLogStorage<AstraTypeConfig> for AstraLogStore

type LogReader = AstraLogReader

Log reader type.

async fn get_log_state( &mut self, ) -> Result<LogState<AstraTypeConfig>, StorageError<u64>>

Returns the last deleted log id and the last log id.

async fn get_log_reader(&mut self) -> Self::LogReader

Get the log reader.

async fn save_vote(&mut self, vote: &Vote<u64>) -> Result<(), StorageError<u64>>

Save vote to storage.

async fn read_vote(&mut self) -> Result<Option<Vote<u64>>, StorageError<u64>>

async fn save_committed( &mut self, committed: Option<LogId<u64>>, ) -> Result<(), StorageError<u64>>

Saves the last committed log id to storage.

async fn read_committed( &mut self, ) -> Result<Option<LogId<u64>>, StorageError<u64>>

Return the last saved committed log id by Self::save_committed.

async fn append<I>( &mut self, entries: I, callback: LogFlushed<AstraTypeConfig>, ) -> Result<(), StorageError<u64>>

where I: IntoIterator<Item = Entry<AstraTypeConfig>> + OptionalSend, I::IntoIter: OptionalSend,

Append log entries and call the callback once logs are persisted on disk.

async fn truncate( &mut self, log_id: LogId<u64>, ) -> Result<(), StorageError<u64>>
