When this was written in the code, Python's Buffer Protocol support was inconsistent across Python versions (specifically on Python 2.7). Since Python 2.7 reached EOL and it was dropped from Numcodecs, the Python Buffer Protocol support has become more consistent. At this stage the `memoryview` object, which Cython also supports, does all the same things that `Buffer` would do for us. Plus it is builtin to the Python standard library. It behaves similarly in a lot of ways. Given this, switch the code over to `memoryview`s internally and drop `Buffer`.

There was a problem hiding this comment.
This seems like a great improvement. Thanks so much @jakirkham!
Unfortunately my Cython isn't really good enough to provide a useful review. But the tests pass! 😆 And we are reducing LoC and simplifying many functions. So seems like a great direction.
Someone who actually groks Cython should review this for real.

@jakirkham any interest in pushing this forward? |
