Trait bee_storage::access::Fetch

pub trait Fetch<K, V>: StorageBackend {
    fn fetch(&self, key: &K) -> Result<Option<V>, Self::Error>;
}

Fetch<K, V> trait extends the StorageBackend with fetch operation for the (key: K, value: V pair); therefore, it should be explicitly implemented for the corresponding StorageBackend.

Required Methods

fn fetch(&self, key: &K) -> Result<Option<V>, Self::Error>

Fetches the value associated with the key from the storage.
