What are ptr and size? I'll probably figure that out when I continue
reading the changes, but a comment would be appropriate here.

"_to_string" is the conventional suffix.

It's better to not have the default case, because that allows the
compiler to warn if the code is not updated when the enum is extended.
The assertion can be after the switch.

The pa_ prefix should only be used for identifiers that are exported in
headers.
You could also avoid introducing any new variable by assigning to the
size variable the final size once it's known. Or is changing function
parameter values too ugly?
Apart from these nitpicks, looks good!
