Feature Highlights

Typehint Validation

The package contains a decorator: validate_types(). Add it to any function you want to validate types for, but make sure you have type hints on your function:

import typing

from easyvalidate import validate_typehints

@validate_typehints()
def foo(x: int, y: typing.Union[int, str]):
    print(x, y)

foo(5, 10) # works
foo(5, 'hello!') # also works
foo(5, []) # error!

The decorator comes with a few arguments:

• all: bool = True: whether to require that all arguments (except self) are type-hinted. It's enabled by default.
• deep: bool = False: whether to recursively validate all members of collections passed to the function. This can be painfully slow on large datasets so it's disabled by default.
