Struct steno::SagaResultErr

pub struct SagaResultErr {
    pub error_node_name: NodeName,
    pub error_source: ActionError,
    pub undo_failure: Option<(NodeName, UndoActionError)>,
}

Provides access to failure details for a saga that failed

When a saga fails, it’s always one action’s failure triggers failure of the saga. It’s possible that other actions also failed, but only if they were running concurrently. This structure describes one of these errors, any of which could have caused the saga to fail (depending on the order in which they completed).

After such a failure, when the saga is unwinding, it’s possible for an undo action to also fail. Again, there could be more than one undo action failure. If any undo actions failed, this structure also describes one of those failures.

Fields

error_node_name: NodeName

name of a node whose action failed

error_source: ActionError

details about the action failure

undo_failure: Option<(NodeName, UndoActionError)>

if an undo action also failed, details about that failure
