Yep that would be me :)
There is also an independent implementation for golang, which even does compression iirc (there is also a golang implementation by me but don't use that. It's way way slower than the other one and unmaintained since I switched to rust development)
Awesome! It's impressive that it's decently close in performance with no unsafe code. Thanks for your hard work!
And that Go implementation is pretty fast too! That's quite impressive.
Sadly it does have one place with unsafe code. I needed a ringbuffer with an efficient "extend from within" implementation. I always wanted to contribute that to the standard library to actually get to no unsafe.
Ah, I saw a PR from like 3 years ago that removed it, so it looks like you added it back in for performance.
Have you tried contributing it upstream? I'm not a "no unsafe" zealot, but in light of the xz issue, it would be nice.
I didn't yet just because I didn't get around to it (and because I am not sure the std lib even wants this feature).
I don't think the two relate. I wouldn't drop any dependency, the ringbuffer is implemented in the same repo.
Yeah, they're not really related. I'm just thinking there might be more scrutiny on compression due to the exploit.
That said, yours doesn't support encoding anyway, so it's kind of moot.
