Class Ticket<T>

Readonlyid

status

• get status(): TicketStatus

  Returns TicketStatus

signal

• get signal(): AbortSignal

  Returns AbortSignal

isCancelled

• get isCancelled(): boolean

  Returns boolean

isSettled

• get isSettled(): boolean

  True once this ticket has reached a terminal state by any path — a normal done transition or cancel() (which resolves the ticket directly, bypassing done). A terminal-event emitter must check this before firing, or a result racing a concurrent cancel() can emit a second, contradictory terminal event for the same ticket.

  Returns boolean

on

  Parameters

  • event: "done"
