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.

funny indeed. i changed all my projects to use tinyvec

"pure safe crates"
I've seen the cost of zeroing memory be measurable, or maybe significant enough to care about, but I've never seen 90% of cycles spent on it, the only case I know of that gets close is creating an empty TinyVec versus an empty SmallVec with an inline buffer of 256 bytes. In my opinion that's an unreasonably large inline buffer. At inline buffers of 128 bytes and below, the overhead is less than 50%, and that's on a microbenchmark of the Default impl; the effect is rapidly diluted in a real program.

single-producer single-consumer concurrent queue
My point is that "implementation that doesn't use unsafe" is not necessarily always slower than "implementation that does use unsafe". Often people assume that this is the case, and it isn't. tinyvec currently beats smallvec in more than a few benchmarks. Not all, but some. And this sometimes visible to users. The point is that if you want speed, you don't necessarily need to give up any safety at all. Most differences in performance are due to the amount of effort or expertise that has been spent on the codebase, not the amount of unsafe in it.

Now that the long-awaited const generics (MVP) have come to stable in 1.51, what crates are going to gain the most from it?
https://github.com/Lokathor/tinyvec will definitely benefit, although not as much as something currently relying on typenum.
