Expose the Pythonizer and Depythonizer

[sandhose]

This exposes the Pythonizer and Depythonizer structs, adding documentation to them and to their public methods. It also adds methods to create a Pythonizer.

Fixes #30

Thanks for this, and sorry for the delayed review.

Overall I'm totally fine with adding this.

Would you be willing to add some tests for this functionality, maybe using serde_path_to_error, so that we can be sure that the pythonize public API will continue to support your use case going forward?

What's the status on this PR? I think it's important we get this merged!

Would you be willing to add some tests for this functionality, maybe using serde_path_to_error, so that we can be sure that the pythonize public API will continue to support your use case going forward?

It's not necessary as serde_path_to_error just requires that the (de)serializer are public and implement the relevant traits from serde

Also PythonizeDefault isn't public, which breaks Pythonizer::new

[davidhewitt]

Still waiting for tests.

It's not necessary as serde_path_to_error just requires that the (de)serializer are public and implement the relevant traits from serde

I disagree, without tests I could easily make these types not public by accident in a future release. All a test would need to do is make an example use of serde_path_to_error. That would be sufficient to function as a guard against me removing these.

@Waelwindows, If you'd like to see this merged, perhaps you would be willing to push a copy of this PR with a test added please?
