SimpleResult<E>

SimpleResult<E> = { ok: true; } | { ok: false; error: E; }

A lightweight discriminated union for success/failure outcomes.

Use this when you need a typed return value without the full Result<T, E> class from Zygos. No methods, no runtime cost, just a plain object.

function save(data: string): SimpleResult {
  if (data.length > 1000) {
    return { ok: false, error: 'Payload too large' }
  }
  return { ok: true }
}

const result = save(payload)
if (!result.ok) {
  console.error(result.error)
}
