isHandled(data: T): boolean

https://docs.evt.land/api/evt/ishandled

Test if posting a given event data will have an effect.

Return true if: -There is at least one handler matching this event data ( at least one handler's callback function will be invoked if the data is posted. ) -Handlers could be will be detached if the event data is posted.

detach<CtxResult>(ctx: CtxLike<CtxResult>): Handler<T, any, CtxLike<CtxResult>>[]
