Implementations

impl Database

pub fn cork(&self) -> Cork

Open a coalescing window without forcing a flush when it closes.

Per-write WAL flushing is suppressed for the guard’s lifetime; the buffered records are left for the next uncorked write (or RocksDB) to flush. Use when the burst need not be durable at any particular point.

pub fn cork_and_flush(&self) -> Cork

Open a coalescing window that flushes the WAL to the OS on drop.

Behaves like cork, but the accumulated WAL is pushed to the OS (without an fsync) as the guard drops, bounding the buffered window to the burst.

pub fn cork_and_sync(&self) -> Cork

Open a coalescing window that syncs the WAL to disk on drop.

Behaves like cork_and_flush, but the WAL is fsynced as the guard drops, so the burst is durable against power loss once the guard has gone.

impl Database

pub async fn open(server: &Arc<Server>) -> Result<Arc<Self>>

Load an existing database or create a new one.

pub fn get(&self, name: &str) -> Result<&Arc<Map>>

pub fn open_cf(&self, name: &'static str) -> Result<Option<Arc<Map>>>

Opens a column family not described in MAPS, for migration reads of a foreign database’s families; None only when the family is absent.

pub fn iter( &self, ) -> impl Iterator<Item = (&&'static str, &Arc<Map>)> + Send + '_

pub fn keys(&self) -> impl Iterator<Item = &&'static str> + Send + '_

pub fn is_read_only(&self) -> bool

pub fn is_secondary(&self) -> bool

Trait Implementations

impl Index<&str> for Database

type Output = Arc<Map>

The returned type after indexing.

fn index(&self, name: &str) -> &Self::Output

Performs the indexing (container[index]) operation.
