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.

Hey Rustaceans! Got a question? Ask here (8/2023)!
It's pretty common to avoid macros as they can seem too magical a lot of the time. And with traits, there's experiments like miniserde which specifically avoid monomorphization overhead. I also see people who want to avoid having lots of dependencies relatively often.

venial 0.1 - A lightweight alternative to syn
Right now, the next step would be to try to reimplement miniserde with venial, and publish benchmarks.

The Serde Rust Framework
The only downside is compile time bloat.
Serde generates heaps and heaps of generic code. This gets optimized away to be very efficient, but it can be quite cumbersome.
Ever tried working on a crate with hundreds or thousands of de/serializable types? Compile times shoot through the roof really quickly.
The maintainer of serde also created `miniserde` [1], which uses dynamic dispatch and can have 4x compile time improvements.
Due to Rusts lack of orphan instances you really depend on a pervasive standard for serializiation which is used by all libraries, so the ecosystem is really locked in to serde by now.

Rust devs push back as Serde project ships precompiled binaries
The precompiled binary is not a sandboxed WASM binary. Despite the name "watt" it has nothing to do with https://github.com/dtolnay/watt . You can look at the actual code to see for yourself.

syn v2.0.0 released
* Related: watt is one approach to pre-compile proc-macro crates using WASM.

My first year with Rust: The good, the bad, the ugly
In addition to thiserror and anyhow, our resident superhuman Rust-improving Robot, dtolnay, also developed an experiment in distributing precompiled proc macros as WebAssembly named Watt and, though I never bothered to create a Zulip account so I don't know what was said, I'm told there has been discussion around the idea of implementing something in that vein.

Rust is coming to the Linux kernel
I think when we have Cranelift, Mold, and maybe Watt all working together then compile times will basically be a non-issue. It'll be a few years though.

Check out https://github.com/dtolnay/watt - it's a really interesting solution to the problem!

Backdooring Rust crates for fun and profit
I really like the idea of Watt: https://github.com/dtolnay/watt Run macros in a wasm sandbox so they can't touch anything you don't explicitly allow.

NPM malware and what it could imply for Cargo
I really wish there was more interest in getting something like Watt upstreamed.
