This release has been yanked by its maintainers, and will be ignored by installers, except when explicitly specified.
Consider using release 2.2.1 instead.
Reason given by maintainers: Broken build
typing-validation is a library to perform runtime validation of Python objects using type hints.
Install
You can install the latest release from PyPI as follows:
pip install --upgrade typing-validationPlease note that v2.0.0 introduces breaking changes to the API, with support restricted to Python 3.14+.
Usage
The core functionality of this library is provided by the validate function:
>>> from typing_validation import validate
The validate function is invoked with a value and a type as its arguments and it returns nothing when the given value is valid for the given type:
>>> validate(12, int) True # no error raised => 12 is a valid int
If the value is invalid for the given type, the validate function raises a TypeError:
>>> validate(12, str) TypeError: Runtime validation error raised by validate(val, t), details below. For type <class 'str'>, invalid value: 12
For nested types (e.g. parametric collection/mapping types), the full chain of validation failures is shown by the type error:
>>> validate([0, 1, "hi"], list[int]) TypeError: Runtime validation error raised by validate(val, t), details below. For type list[...], invalid value at idx: 2 For type <class 'int'>, invalid value: 'hi'
The function is_instance is a variant of the validate function which returns False in case of validation failure, instead of raising TypeError:
>>> from typing_validation import is_instance >>> is_instance([0, 1, "hi"], list[int]) False
