Cancel Function Callback

[sancar]

When a workflow is canceled, there is no cleanup function that we call similar to failureFunction. It could be the case that
a cleanup is needed upon cancellation.

Option 1:

export const { POST } = serve(
  async (context) => {}, 
  {
    failureFunction: async ({context, failStatus, failResponse, failHeaders}) => {
    },
    cancellationFunction: async ({context}) => {
    }
  }
);

Option 2:

export const { POST } = serve(
  async (context) => {}, 
  {
    failureFunction: async ({context, failStatus, failResponse, failHeaders, isCanceled}) => {
      if (isCanceled) {
        // Run failure cleanup logic
      } else {
        // Run cancel cleanup logic
      }
    },
  }
);

@mehmet.tokgoz : I would personally prefer the first option as it is clearer. I like that the failureFunction is exclusively for failures.

+1 for option 1 as well 🙌 So far really enjoy using Upstash and the code design of the SDK. Having separate function callback to separate error and cancellation makes a lot of sense!
