Lightweight validation for python objects.

strictobject

Lightweight validation for python objects.

Examples:

1. Simple validation

   from strictobject import StrictObject
   
   class A(StrictObject):
       num: int
   
   A(num=0)  # ok
   A(num=42)  # ok
   A(num="not an int")  # will throw a TypeError
   

2. Custom validation

   from strictobject import StrictObject
   
   class B(StrictObject):
       fortytwo: Union[int|str]
       # custom validators must by named by "validate_" followed by
       # the class attribute name, and they should return a bool
       def validate_fortytwo(self, val) -> bool:
           return int(val) == 42
   
   B(num=42)  # ok
   B(num="42")  # ok
   B(num=123)  # will throw a TypeError
   

Works with all built-in types, and with special types List, Union, Optional from package typing.
