Set of method for basic storage providers to implement.

Required Methods

fn set<'life0, 'async_trait>(
    &'life0 self,
    scope: Arc<[u8]>,
    key: Arc<[u8]>,
    value: Arc<[u8]>
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Set a key-value pair, if the key already exist, value should be overwritten

fn get<'life0, 'async_trait>(
    &'life0 self,
    scope: Arc<[u8]>,
    key: Arc<[u8]>
) -> Pin<Box<dyn Future<Output = Result<Option<Arc<[u8]>>>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Get a value for specified key, it should result in None if the value does not exist

fn delete<'life0, 'async_trait>(
    &'life0 self,
    scope: Arc<[u8]>,
    key: Arc<[u8]>
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Delete the key from storage, if the key doesn’t exist, it shouldn’t return an error

fn contains_key<'life0, 'async_trait>(
    &'life0 self,
    scope: Arc<[u8]>,
    key: Arc<[u8]>
) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>where
    Self: 'async_trait,
    'life0: 'async_trait,

Check if key exist in storage
