Interface AttemptHandle<T>

Handle returned by attempt(). The caller decides whether the speculative work survives (commit) or is rolled back (discard).

interface AttemptHandle<T = any> {
    result: T;
    signal: AbortSignal;
    commit(): void;
    discard(): void;
}

Properties

result: T

Whatever the attempt callback returned (often a Promise).

signal: AbortSignal

The AbortSignal passed to the attempt callback. discard() aborts it, so async speculative work wired to it is cancelled.

commit(): void
Mark the attempt as committed in history (records a checkpoint).

Returns void
- Defined in spektrum.d.ts:127

discard(): void
Replay back to before the attempt (aborting signal); the entries land on forks on the next mutation.

Returns void
- Defined in spektrum.d.ts:130
