Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Rewrite the VP9 codec library in Rust
As already mentioned, bounds checks won't necessarily cause that much overhead. When I rewrote my small image processing library from C to Rust ([1]), I only had to use unchecked array access in one hot loop to get overall performance equivalent to C code.

Speed of Rust vs. C
To practise Rust, I rewrote my small C99 library in it [1]. Performance is more or less the same, I only had to use unchecked array access in one small hot loop (details in README.md). I haven't ported multithreading yet, but I expect Rust's Rayon parallel iterators will likewise be comparable to OpenMP.

Ask HN: Good book to learn modern networking?
Once you're past the fundamentals, if find yourself interested in high-performance networking, I recommend looking into userspace networking and NIC device drivers. The Intel 82599ES has a freely available (and readable!) data sheet, DPDK has a great book, ixy [1] has a wonderful paper and repo. It's a great way to go beyond the basics of networking and CPU performance. It's even more approachable today with XDP – you don't need to write device-specific code.

Looks like you're compiling C code with -O2. Does Rust build set -O3 on clang? Did you try -O3 with C? I know it's not guaranteed to be faster, just curious.
