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.

Best format for high-performance Serde?
I've been enjoying postcard as a lightweight efficient binary serialization.
-
Ractor: not just another actor framework
That said, postcard is not a self describing format (so everyone needs the same schema, no changes allowed), but I do have a tracking issue open for ways to handle this in the future.
-
Are there any serialization crates that do Varint encoding without Zigzag encoding?
For example, look at the Postcard serializer for inspiration.

Hey Rustaceans! Got a question? Ask here! (51/2022)!
Serde should be no_std, I have used it embedded with crates such as postcard. You can see how postcard disables default features of serde here : https://github.com/jamesmunns/postcard/blob/main/Cargo.toml

jemi: a compact JSON serializer for embedded systems
Another option that may work for some is SerDe on rust. You just write a struct with the fields you want #[derive(Serialize, Deserialize)] above it, and if codegens the functions to deserialize that struct from JSON and serialize it back. Example looks like this https://docs.rs/serde_json/latest/serde_json/#creating-json-by-serializing-data-structures (but you have to use serde-json-core if you don’t have an allocator). Can also easily reserialize to something small like postcard that’s meant for embedded storage.

Karmem: A fast binary serialization format faster than Google Flatbuffers

postcard seems like it would be particularly strong for the wasm use case as it produces small messages that are light in memory.

Spinkube: Running WASM in Kubernetes
This reminds me of Lunatic [1], an Erlang-inspired runtime for WebAssembly. Unfortunately it seems like development stalled some months ago.

Spin 2.0 – open-source tool for building and running WASM apps
you can check out https://github.com/lunatic-solutions/lunatic for that
-
Flawless – Durable execution engine for Rust
Very cool, and the approach demonstrated might be of interest to a similar problem we have in Ambient (our WASM game runtime that has competing processes that may need to retry interactions.)
That being said - what’s the relation to Lunatic [0]? Are you still working on Lunatic? Is this a side project? Or is it something completely separate?

Async Rust Is A Bad Language
Curious too. I follow Lunatic [0] as a candidate for future use, and also wasmCloud [1].

- A WASI VM?
- how can I add dynamic loading to do "plugins" for my Rust app?

Elixir and Rust is a good mix
There's a couple of Rust libs and frameworks inspired on Erlang in 'best of both worlds' attempts, such as https://lunatic.solutions
I found others like Lunatic before, but cannot remember right now.
-
Anything close beam/otp for other languages?
There is a really good initiative called Lunatic : https://lunatic.solutions/
