pub struct SstCursor { /* private fields */ }

A cursor over an Sst.

Trait Implementations

impl Clone for SstCursor

fn clone(&self) -> SstCursor

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Cursor for SstCursor

type Error = Error

The type of error returned by this cursor.

fn seek_to_first(&mut self) -> Result<(), Error>

Seek past the first valid key-value pair to a beginning-of-stream sentinel.

fn seek_to_last(&mut self) -> Result<(), Error>

Seek past the last valid key-value pair to an end-of-stream sentinel.

fn seek(&mut self, key: &[u8]) -> Result<(), Error>

Seek to this key. After a call to seek, the values of [key] and [value] should return the sought-to key or the key that’s lexicographically next after key.

fn prev(&mut self) -> Result<(), Error>

Advance the cursor forward to the lexicographically-previous key.

fn next(&mut self) -> Result<(), Error>

Advance the cursor forward to the lexicographically-next key.

fn key(&self) -> Option<KeyRef<'_>>

The key where this cursor is positioned, or None if the cursor is positioned at the bounds.

fn value(&self) -> Option<&[u8]>

The value where this cursor is positioned, or None if the cursor is positioned at a tombstone or the limits of the cursor.

fn key_value(&self) -> Option<KeyValueRef<'_>>

Return a KeyValueRef corresponding to the current position of the cursor. By default this will stitch together the values of key() and value() to make a KeyValueRef.

impl Debug for SstCursor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Sst> for SstCursor

fn from(table: Sst) -> Self

Converts to this type from the input type.
