Required Methods

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

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

fn as_connection_like(&mut self) -> &mut dyn ConnectionLike

Explicit upcast of self reference. Rusts current vtable layout doesn’t allow for an upcast if trait A, trait B: A, so that Box<dyn B> as Box<dyn A> works. This is a simple, explicit workaround.
