Struct InactiveStore

pub struct InactiveStore;

A store which does not actually store anything - used for caching views.

Trait Implementations

impl ReadableKeyValueStore for InactiveStore

async fn find_key_values_by_prefix( &self, _key_prefix: &[u8], ) -> Result<Vec<(Vec<u8>, Vec<u8>)>, Self::Error>

Finds the (key,value) pairs matching the prefix. The prefix is not included in the returned keys.

const MAX_KEY_SIZE: usize = 0usize

The maximal size of keys that can be stored.

fn max_stream_queries(&self) -> usize

Retrieve the number of stream queries.

async fn read_value_bytes( &self, _key: &[u8], ) -> Result<Option<Vec<u8>>, Self::Error>

Retrieves a Vec<u8> from the database using the provided key.

async fn contains_key(&self, _key: &[u8]) -> Result<bool, Self::Error>

Tests whether a key exists in the database

async fn contains_keys( &self, _keys: Vec<Vec<u8>>, ) -> Result<Vec<bool>, Self::Error>

Tests whether a list of keys exist in the database

async fn read_multi_values_bytes( &self, _keys: Vec<Vec<u8>>, ) -> Result<Vec<Option<Vec<u8>>>, Self::Error>

Retrieves multiple Vec<u8> from the database using the provided keys.

async fn find_keys_by_prefix( &self, _key_prefix: &[u8], ) -> Result<Vec<Vec<u8>>, Self::Error>

Finds the key matching the prefix. The prefix is not included in the returned keys.

fn read_value<V: DeserializeOwned>( &self, key: &[u8], ) -> impl Future<Output = Result<Option<V>, Self::Error>> + Send + Sync

Reads a single key and deserializes the result if present.

fn read_multi_values<V: DeserializeOwned + Send + Sync>( &self, keys: Vec<Vec<u8>>, ) -> impl Future<Output = Result<Vec<Option<V>>, Self::Error>> + Send + Sync

Reads multiple keys and deserializes the results if present.

impl WithError for InactiveStore

type Error = InactiveStoreError

The error type.

impl WritableKeyValueStore for InactiveStore

const MAX_VALUE_SIZE: usize = 0usize

The maximal size of values that can be stored.

async fn write_batch(&self, _batch: Batch) -> Result<(), Self::Error>

Writes the batch in the database.

async fn clear_journal(&self) -> Result<(), Self::Error>

Clears any journal entry that may remain. The journal is located at the root_key.
