impl TierStorage for WarmStorage

fn get( &self, _table: EntryKind, _key: &[u8], _version: CommitVersion, ) -> Result<Option<CowVec<u8>>>

Get the value for a key at or before the given version.

fn set( &self, _version: CommitVersion, _batches: HashMap<EntryKind, Vec<(CowVec<u8>, Option<CowVec<u8>>)>>, ) -> Result<()>

Write entries to multiple tables atomically at the given version.

fn range_next( &self, _table: EntryKind, _cursor: &mut RangeCursor, _start: Bound<&[u8]>, _end: Bound<&[u8]>, _version: CommitVersion, _batch_size: usize, ) -> Result<RangeBatch>

Fetch the next batch of entries in key order at or before version.

fn range_rev_next( &self, _table: EntryKind, _cursor: &mut RangeCursor, _start: Bound<&[u8]>, _end: Bound<&[u8]>, _version: CommitVersion, _batch_size: usize, ) -> Result<RangeBatch>

Fetch the next batch of entries in reverse key order at or before version.

fn ensure_table(&self, _table: EntryKind) -> Result<()>

Ensure a table exists (creates if needed).

fn clear_table(&self, _table: EntryKind) -> Result<()>
