Struct golem_rust::FallibleTransaction

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

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.

In case of fatal errors (panic) and external executor failures it does not perform the compensation actions and the whole transaction gets retried.

Implementations

impl<Err: Clone + 'static> FallibleTransaction<Err>

pub fn execute<OpIn: Clone + 'static, OpOut: Clone + 'static>( &mut self, operation: impl Operation<In = OpIn, Out = OpOut, Err = Err> + 'static, input: OpIn, ) -> Result<OpOut, Err>
