Implementations

impl<Key, Value> Store<Key, Value> where
Key: Hash + Eq + Serialize + DeserializeOwned + Send + 'static,
Value: Serialize + DeserializeOwned + Send + Clone + 'static,

pub fn new(keyed_db: DBMap<Key, Value>) -> Self

impl<Key, Value> Store<Key, Value> where
Key: Serialize + DeserializeOwned + Send,
Value: Serialize + DeserializeOwned + Send,

pub async fn write(&self, key: Key, value: Value)

pub async fn write_all(
&self,
key_value_pairs: impl IntoIterator<Item = (Key, Value)>
) -> Result<(), StoreError>

Atomically writes all the key-value pairs in storage. If the operation is successful, then the result will be a non error empty result. Otherwise the error is returned.

pub async fn remove(&self, key: Key)

pub async fn remove_all(
&self,
keys: impl IntoIterator<Item = Key>
) -> Result<(), StoreError>

Atomically removes all the data referenced by the provided keys. If the operation is successful, then the result will be a non error empty result. Otherwise the error is returned.

pub async fn read(&self, key: Key) -> Result<Option<Value>, StoreError>

pub async fn read_all(
&self,
keys: impl IntoIterator<Item = Key>
) -> Result<Vec<Option<Value>>, StoreError>

Fetches all the values for the provided keys.

pub async fn notify_read(&self, key: Key) -> Result<Option<Value>, StoreError>
