Struct MemStore 

pub struct MemStore { /* private fields */ }

In-memory Store backed by a BTreeMap. Not persistent; durable is a no-op. Useful as the default, for tests, and as a benchmark baseline.

Implementations

impl MemStore

pub fn new() -> Self

Create an empty store.

Trait Implementations

impl Default for MemStore

fn default() -> Self

Returns the “default value” for a type.

impl Store for MemStore

type Error = !

The backend’s error type.

fn get(&self, key: &[u8]) -> Result<Option<Vec<u8>>, Self::Error>

Value for an exact key.

fn seek(&self, from: &[u8]) -> Result<Option<KeyValue>, Self::Error>

Smallest entry whose key is >= from.

fn seek_back(&self, upto: &[u8]) -> Result<Option<KeyValue>, Self::Error>

Greatest entry whose key is <= upto.

fn commit(&self, ops: &[Op<'_>], _durable: bool) -> Result<(), Self::Error>

Apply ops. When durable, do not return until they survive a crash.
