Document that `typing_extensions.Protocol` and `typing.Protocol` don't always play well together (#246)
The typing_extensions
module serves two related purposes:
typing.TypeGuard
is new in Python 3.10, but typing_extensions
allows users on previous Python versions to use it too.typing
module.typing_extensions
uses Semantic Versioning. The major version will be incremented only for backwards-incompatible changes. Therefore, it's safe to depend on typing_extensions
like this: typing_extensions >=x.y, <(x+1)
, where x.y
is the first version that includes all features you need.
typing_extensions
supports Python versions 3.7 and higher.
See the documentation for a complete listing of module contents.
To run tests, navigate into the src/
directory and run test_typing_extensions.py
.
