Struct sst::Sst

pub struct Sst { /* private fields */ }

An Sst represents an immutable sorted string table.

Implementations

impl Sst

pub fn new<P: AsRef<Path>>(_options: SstOptions, path: P) -> Result<Self, Error>

Open the provided path using options.

pub fn from_file_handle(handle: FileHandle) -> Result<Self, Error>

Create an Sst from a file handle.

pub fn approximate_size(&self) -> usize

Approximate size of the sst’s memory footprint.

pub fn cursor(&self) -> SstCursor

Get a new cursor for the Sst.

pub fn metadata(&self) -> Result<SstMetadata, Error>

Get the Sst’s metadata. This will involve reading the first and last keys from disk.

pub fn fast_setsum(&self) -> Setsum

Return the setsum stored in the final block of the sst.

pub fn inspect(&self) -> Result<(), Error>

Inspect the sst by printing its internal structure.

pub fn load( &self, key: &[u8], timestamp: u64, is_tombstone: &mut bool ) -> Result<Option<Vec<u8>>, Error>

pub fn range_scan<T: AsRef<[u8]>>( &self, start_bound: &Bound<T>, end_bound: &Bound<T>, timestamp: u64 ) -> Result<BoundsCursor<PruningCursor<SstCursor, Error>, Error>, Error>
