The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

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.

Security advisory: malicious crate rustdecimal | Rust Blog
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.

Way to get NVM working in CI/CD systems
- Rust projects are built with https://github.com/cargo2nix/cargo2nix. We chose cargo2nix to get incremental builds, meaning that dependency builds can be shared between our Rust projects and that not all dependencies have to be rebuilt when adding/updating/removing dependencies from a project.

[Blog post]: Scaling Rust builds with Bazel
We used cargo2nix to generate top-level Cargo.nix file that we committed to the repository (we didn't allow generating nix files on CI for security and reproducibility reasons).

Nix & Rust - cargo2nix 0.11.0 released
There's a cross compile example that works for at least 3-4 targets on Linux and uses proc macros. Pretty sure the situation you described is no more complex.

Rust nix develop & nix build - cargo2nix 0.11.0 released
Release notes. Last announced release was 0.9.0.

How Go Mitigates Supply Chain Attacks
Nix already solves this problem and can handle dependencies and building projects across a range of languages (including Rust via Cargo2nix) and reproducible machine configuration.

Is using crates more safe than using npm?
Building with nix, for instance with cargo2nix (https://github.com/cargo2nix/cargo2nix), could be safer if sandboxing is enabled.
