anti-r is a spatial data structure that can outperform R-Trees in a few cases.

Fix-rat is a rational number with a denominator chosen at compile time.

I tried writing a Chunked-List data structure and made all the mistakes while using unsafe for that.

Optimath is an experimental const generics based linear algebra library that works without any allocations in no_std and utilizes simd. So now you can do fancy maths on embedded.

I noticed that I quite enjoy writing libraries that support no_std environments, even though I myself don't even work on embedded.
