StatefulStepScope

class StatefulStepScope<R, S>(stateHolder: AtomicReference<S>, val result: R?)

Scope for forward step execution, providing access to saga state.

This scope is the receiver for forward action lambdas, enabling:

Reading current state via state property
Updating state via updateState function
Accessing previous step's result via result property

Example

first `do` "take-payment" with { cart ->
    // Read current state
    val currentAmount = state.paymentAmount

    // Update state
    updateState { it.copy(paymentAmount = payment.amount) }

    // Access previous result (null for first step)
    val previousOrder = result

    createOrder(cart)
}
