There's a more complete module description for the encoder and decoder now. Both versions get appended by rustdoc, which looks wrong and shouldn't be necessary.
There's some redundancy here with the docstring examples/tests, but that's entirely on purpose:
Unfortunately, it seems that the coverage tool has trouble recognizing calls from within the docstring examples. It's an unstable feature - maybe that's why?
Even with these tests, the tool still doesn't properly detect everything. Regardless, function coverage is 100% when running the coverage tool locally.
