This PR adds a
signal
option to therun
method. Normally, therun
method creates a prediction and then waits until it finishes. Because it doesn't return an intermediate value (unlikepredictions.create
), there's no mechanism for stopping and canceling the prediction until after it's completed.This PR also adds a
stop
parameter to thewait
method, which is used in the implementation of the abort signal. With this change, you can now pass a function as an argument towait
that takes a prediction as an argument and returns a promise for a Boolean. If this callback returnstrue
, then thewait
stops polling and returns. This callback also provides a way to monitor progress as the predictions updates.
