arcane-typing
This package provides advanced typing patterns for Python projects that use ty.
Features
Core utilities
TypeOf[expr]can be used to obtain ty's inferred type for an expression in a type annotation or type alias.Top[T]can be used to refer to the top-materialization ofT.Bottom[T]can be used to refer to the bottom-materialization ofT.
TypedDict features
TypeOf[Keys[T]]gives a union of string literals for the keys that can appear in aTypedDictT.
Type Narrowing
hasattr_of_type(obj, "name", T)narrowsobj.nameto typeTif the attribute exists and if it is an instance ofT(which can be a class or a union of classes)is_sequence_of(obj, T)checks thatobjis a sequence and that every element is an instance ofT(which can be a class or a union of classes). It narrowsobjtoSequence[T]on success.
