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.

OpenD, a D language fork that is open to your contributions
That's because you're looking at a wrapper around the actual implementation (which lives in an external package). Notice "use hashbrown::hash_map as base;" at the top.
There's far more unsafe there: https://github.com/rust-lang/hashbrown/blob/f2e62124cd947b5e...

I just published my first crate: `identified_vec` - I would love some input! PR's are most welcome.
You might want to check out how popular ecosystem crates do some of these things. Particularly relevant to you are probably crates providing collections, such as smallvec, hashbrown, or indexmap.

When Zig Outshines Rust – Memory Efficient Enum Arrays
Thanks, great point indeed. I am looking into this https://github.com/rust-lang/hashbrown
The way I think about it -- rather naively, I suppose -- is that I care more about the references cells make to each other than the actual grid of cells displayed on a table. The latter feels more like a "view" of the data than an actual data structure?
This also seems to align with the relative priority of (sorted from highest to lowest): figuring out the order of evaluation, calculating those evaluations, and finally displaying the results of the evaluation

This Week in Rust # 500!!
updated std's hashbrown dependency to 0.14 which contains some optimizations

Crust of Rust: std::collections [video]
The std hashmap is actually very fast and uses state of the art hashmap design, namely because it's implemented by hashbrown

Deduplicating a Slice in Go
I believe Rust uses hashbrown as the underlying implementation now. This just calculates the number of buckets based on the number of items requested:
https://github.com/rust-lang/hashbrown/blob/009969a860290849...
Is it really the case that rehashing can guarantee that the number of buckets allocated will be sufficient for any given set of keys? In principle you could fail to rehash in a way that reduces collisions after k attempted rehashings.

Blog Post: Rust Is a Scalable Language
For example, since the hashbrown crate is marked with #![no_std], it can be used as a dependency for the standard library.

Hey Rustaceans! Got a question? Ask here (6/2023)!
To implement something that cannot be expressed in safe Rust, or at least cannot be expressed succinctly in safe Rust, like fundamental datastructures. The hashbrown crate contains a lot of unsafe code, but it's such high quality that it's now the backing implementation for std::collections::HashMap.
