Trait Implementations

impl<const ENTRIES: usize, const KEY_LEN: usize, const VALUE_LEN: usize> Default for MemoryKeyValueStore<ENTRIES, KEY_LEN, VALUE_LEN>

fn default() -> Self

Returns the “default value” for a type.

impl<const ENTRIES: usize, const KEY_LEN: usize, const VALUE_LEN: usize> KeyValueStore for MemoryKeyValueStore<ENTRIES, KEY_LEN, VALUE_LEN>

type Error = MemoryStoreError

async fn load( &self, key: &[u8], buf: &mut [u8], ) -> Result<Option<usize>, Self::Error>

Load a value into buf, returning the stored length when present.

async fn store(&self, key: &[u8], value: &[u8]) -> Result<(), Self::Error>

Store a value for key.

async fn delete(&self, key: &[u8]) -> Result<(), Self::Error>

Delete any stored value for key.
