Struct FallibleTransaction 

Source 
pub struct FallibleTransaction<Err> { /* private fields */ }
Expand description

FallibleTransaction is a sequence of operations that are executed in a way that if any of the operations fails all the already performed operation’s compensation actions got executed in reverse order.

Panics and external executor failures do not trigger compensation. Recovery follows ordinary durable replay, without rewinding the transaction.
