    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait,

Retrieve the user data for a given user

fn get_user_state<'life0, 'life1, 'async_trait>(
    &'life0 self,
    username: &'life1 AkdLabel,
    flag: ValueStateRetrievalFlag
) -> Pin<Box<dyn Future<Output = Result<ValueState, StorageError>> + Send + 'async_trait>>where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait,

Retrieve a specific state for a given user

fn set<'life0, 'async_trait>(
    &'life0 self,
    record: DbRecord
) -> Pin<Box<dyn Future<Output = Result<(), StorageError>> + Send + 'async_trait>>where
    'life0: 'async_trait,
    Self: 'async_trait,

Set a record in the database

fn batch_set<'life0, 'async_trait>(
    &'life0 self,
    records: Vec<DbRecord>,
    _state: DbSetState

    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait,
