Required Methods

fn next<'life0, 'life1, 'life2, 'async_trait>( &'life0 mut self, ddl_ctx: &'life1 DdlContext, ctx: &'life2 mut DropDatabaseContext, ) -> Pin<Box<dyn Future<Output = Result<(Box<dyn State>, Status)>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Yields the next State and [Status].

fn as_any(&self) -> &dyn Any

Returns as Any.

Provided Methods

fn recover(&mut self, _ddl_ctx: &DdlContext) -> Result<()>

The hook is called during the recovery.
