Expand description

Set of method for basic storage providers to implement.

Required Methods§

Source

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

Source

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

Source

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

Source

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
