Retryer usage

gistfile1.coffee

# Create the wrapped function with 5 retries
command = @commands.retry('connectToProvider', attempts: 5)

# Create the wrapped function with unlimited retries
command = @commands.retry('connectToProvider')

# Essentially a promise is returned with another method attached
promise = command('yahoo', username: 'x', password: 'y')

# Some bad shit happens
promise.cancel()
# no more retries

# Progress is reported when a request (or deferred action) fails and is retried
# - the error object is from the action's fail callback
promise.progress (object) ->
  # error:
  # attempts:
  # interval:
  # message: 

# Called when the retries completely fail or the action is canceled (promise.cancel())
promise.fail (object) -> 
  # error:
  # attempts:
  # interval:
  # message:

# The action succeeded
promise.done (response) ->
      

This looks like the caller of the retry is canceling the promise, don't get how the wrapped function is canceling the promise.

Depends what you are trying to do. Do you want the retrier to stop on its own - or under some condition?

That is what cancels the retry
