PhaseEventMap

Strict-event-emitter payload map for a lifecycle: phase + prefix startstart/completecomplete events carry no payload; the ${Prefix}:error${Prefix}:error event carries the thrown error.

type PhaseEventMap<
    Prefix extends string,
    Phases extends number[]
> = {
    [K in PhaseEvents<
        Prefix,
        Phases
    >]: K extends `${string}:error`
        ? readonly [error: unknown]
        : readonly [];
};
