module concrete.ml.sklearn.protocols

Protocols.

Protocols are used to mix type hinting with duck-typing. Indeed we don't always want to have an abstract parent class between all objects. We are more interested in the behavior of such objects. Implementing a Protocol is a way to specify the behavior of objects.

To read more about Protocol please read: https://peps.python.org/pep-0544
