def self.cancel(client, id)
  res = client.action_state.cancel(id, meta: {block: false})

  if res.ok? && res.action.blocking? && res.meta[:action_state_id]
    res.meta[:action_state_id]

  else
    res
  end
end

.wait_for_completion(client, id, interval: 15, update_in: 3, timeout: nil) {|state| ... } ⇒ Boolean, ...

Block until the action is completed or timeout occurs. If the block is given, it is regularly called with the action’s state.

Parameters:

  • interval (Float) (defaults to: 15) —

    how often should the action state be checked

  • timeout (Integer) (defaults to: nil) —

    timeout in seconds

Yield Parameters:

Returns:

  • (Boolean) —

    when the action is finished

  • (nil) —

    when timeout occurs

  • (Response) —

    if the action was cancelled and the cancel itself isn’t blocking

  • (Integer) —

    id of cancellation if the action was cancelled, cancel is blocking and no cancel block is provided
