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.

WASM file size for a minimal #![no_std] library too large
I was getting a large .wasm file size for my no_std library, so I decided to investigate by setting up the smallest possible no_std library with wee_alloc as the global allocator: https://github.com/kobby-pentangeli/min-no-std

Rust: A Critical Retrospective
> we did not have Vec because we were no-std + stable so we literally had to use arrays
It's true that Vec isn't available in a no-std context, but don't think it follows that arrays are the only other option - see heapless for one example: https://github.com/japaric/heapless
I also agree with some of the ancestors: the post seems to say that the Rust language couldn't handle arrays with more than 32 elements, and (as someone who's written a fair bit of no-std Rust before const generic) that doesn't seem right. At first, this did seem awkward to me as well, but in practice I haven't found it to be a significant limitation. Was there a particular scenario where it wasn't feasible to wrap a >32 element array in your own type and implement Default on 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?

Writing a proposal to use Rust at work
heapless has both SPSC and MPMC channels that work on embedded
What are some alternatives?
cortex-m-quickstart - Template to develop bare metal applications for Cortex-M microcontrollers
tinyvec - Just, really the littlest Vec you could need. So smol.
wee_alloc - The Wasm-Enabled, Elfin Allocator
blisp - A statically typed Lisp like scripting programming language for Rust.
scapegoat - Safe, fallible, embedded-friendly ordered set/map via a scapegoat tree. Validated against BTreeSet/BTreeMap.
utils - Utility crates used in RustCrypto
regex-automata - A low level regular expression library that uses deterministic finite automata.
cassette - A simple, single-future, non-blocking executor intended for building state machines. Designed to be no-std and embedded friendly.
biscuit - Biscuit research OS
uom - Units of measurement -- type-safe zero-cost dimensional analysis
KEEP - Kotlin Evolution and Enhancement Process
snapbox - Snapshot testing for CLIs
