Promises¶

Promises are a way of running different kinds of tasks with Earwax.

The term is shamelessly stolen from JavaScript, and Earwax’s interpretation is largely the same: A promise is instantiated, and set to run. At some point in the future, the promise will have a value, which can be listened for with the on_done() event.

This part of the tutorial contains some further thoughts on using the different types of promise Earwax has to offer.
