This is a validation companion to dataclasses.
It adds the strict method to the dataclass to validate the types are correct.
Usage:
from dataclasses import dataclass
from strictclasses import strict
@strict
@dataclass
class Foo:
bar: int
f = Foo('3')
f.strict() # -> TypeError: bar is not an instance of <class 'int'>from strictclasses import strictclass
@strictclass
class Foo:
bar: int
f = Foo('3') # -> TypeError: bar is not an instance of <class 'int'>
f = Foo(3)
f.bar = 3.3 # -> TypeError: bar is not an instance of <class 'int'>
