    S: State<Context = C, Error = E>,  {
    Reverting {
        step: S,
        source: Option<Arc<E>>,

}

An internal state machine that represents the process of reverting previous progress.

Variants

Reverting

An in-flight State reversion

Fields of Reverting

step: S

the state variant in the process of being reverted

source: Option<Arc<E>>

the original error that triggered the reversion process, if one exists

Reverted

The final state of a successful reversion

Fields of Reverted

source: Option<Arc<E>>

the original error that triggered the reversion process

Failure

The final state of a failed reversion

Fields of Failure

source: Option<Arc<E>>

the original error that triggered the reversion process

error: E

the error that caused the reversion process to fail
