Callback registry

Project Description


[![Build Status](]( [![Documentation Status](]( [![PyPi version](]( [![PyPi downloads](](

[Documentation on ReadTheDocs](

Devolve is a callback registry. Callable objects can be registered against a set of keys. The registry can then be used to delegate a single call across all of the registered callables and to gather all of the returned key/value pairs into a single mapping.

## Features

  • Prevents duplicate registration of the same key.
  • Validation that a callable did not return any extra keys.
  • Validation that a callable returned all of the keys it was registered for.
