The base class for typed descriptors

Descriptors are class data members that collect compile time meta-data about attributes.

In pyre, classes that use descriptors typically have a non-trivial metaclass that harvests them and catalogs them. The base class that implements most of the harvesting logic is {pyre.patterns.AttributeClassifier}. The descriptors themselves are typically typed, because they play some kind of rôle during conversions between internal and external representations of data.
