A database that on top of a raw database operation, implements key notification system.

Required Methods

fn begin_transaction<'a, 'async_trait>( &'a self, ) -> Pin<Box<dyn Future<Output = Box<dyn IDatabaseTransaction + 'a>> + Send + 'async_trait>>

where Self: 'async_trait, 'a: 'async_trait,

Start a database transaction

fn register<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

Register (and wait) for key updates

fn notify<'life0, 'life1, 'async_trait>( &'life0 self, key: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

Notify about key update (creation, modification, deletion)

fn is_global(&self) -> bool

The prefix len of this database refers to the global (as opposed to module-isolated) key space

fn checkpoint(&self, backup_path: &Path) -> Result<()>

Checkpoints the database to a backup directory
