You're the best candidate to maintain this code since you wrote it :-)

Also I personally have near zero skills in Rust as of today so all I can do
is to vaguely keep an eye on the binding's interface and keep in touch
with the changes.

So I suggest you to add a new entry with you as a maintainer (I suggested
something similar to Fujita for some other timer related things) but please
keep us Cc'ed for future changes.

Let me have a last look...

Thanks.
