Trait Implementations

impl Default for MemoryStorage

fn default() -> Self

Returns the “default value” for a type.

impl Storage for MemoryStorage

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

Get a value by key. Returns None if the key does not exist.

fn set(&self, key: &[u8], value: Vec<u8>) -> BoxFuture<'_, Result<(), Error>>

Set a key to a value, overwriting any existing value.

fn increment(&self, key: &[u8], delta: i64) -> BoxFuture<'_, Result<i64, Error>>

Atomically increment a counter by delta, returning the new value. If the key does not exist, it is created with an initial value of delta.

fn list(&self, prefix: &Prefix) -> BoxFuture<'_, Result<KvPairs, Error>>

List all key-value pairs whose keys start with prefix. Returned in arbitrary order.

fn delete(&self, key: &[u8]) -> BoxFuture<'_, Result<(), Error>>

Delete a key. No-op if the key does not exist.
