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.

cargo-udeps 0.1.33 release
I'm releasing cargo-udeps 0.1.33 today. The release marks a big change in the evolution of cargo-udeps, as the default backend is changed from using save-analysis to depinfo. This change was needed because the compiler is removing support for save-analysis. I will remove support for the save-analysis backend entirely in a couple of weeks, when the 1.64 release is made, and I'll update cargo-udeps to the new cargo release.

Why can rust-analyzer not detect unused dependencies?
rust-analyzer only provides a handful of diagnostics by itself, everything else is forwarded from cargo check (if checkOnSave is enabled). Neither tool currently emits a warning for unused dependencies, since it's pretty hard to do, but cargo-udeps can do it (though I'm not sure how reliable it is).
- Is there a tool to remove unused dependencies from a Cargo file?
-
Is the crate dependency becoming a problem?
Maybe an extension to cargo-udeps?
-
Corrode without bloat. Is detecting unnecessary features feasible?
cargo-udeps does a great job at letting us know which dependencies in our `Cargo.toml` are left unused. I am pretty impressed with it.

Reducing Rust Incremental Compilation Times on macOS by 70%
You can also turn off debuginfo completely. Personally, someone who does printf debugging, I mainly need it to debug segfaults, which are really rare in Rust. Sometimes the call stack of a panic is useful as well, but if I need debuginfo I can just re-enable it.

I reduced (incremental) Rust compile times by up to 40%
I think this is unlikely to gain traction. I say that no to discourage you, just to explain.
- The community has an instinctive distrust of closed source or a compiler from an untrusted source. If you’re familiar with the Trusting Trust attack you’ll understand why.
- Dev tools in every language ecosystem are almost always free, unless they involve some kind of hosting. People aren’t used to opening their wallets. Look the experience of the guy who built the mold linker(https://github.com/rui314/mold). Far superior to the state of art, improves incremental compiles a lot, widely applicable across ecosystems (C, C++, Rust), CPU architectures and Operating Systems. You don’t even have to modify your compiler, just need to point to his linker. He’s even giving it away for free for personal use. But still, almost no one uses it. The inertia of the established options is really high.
- It’s not complex enough. Think about the complexity involved in the cranelift backend. No one can seriously recreate the efforts of bjorn3. If we could have, we would have. But the idea idea here can be recreated, especially by the experts who already built incremental compilation into rustc.
- But if your solution is truly complex, like the parallel frontend, the burden of maintaining a fork would be too high. You’d have to spend all your time rebasing.
Again I’m not trying to discourage you, just stating the difficulties of making a business in the dev tools space. You would be better off contributing this excellent work to the community and trying a different tack.

Monetizing Developer Tools
I assume this submission is trying to highlight the specific message (2023-01-24) : https://github.com/rui314/mold/issues/190#issuecomment-14028...
Fyi... the author wrote a more expansive blog post about selling dev tools a few months later (2023-06-06) and there was a related HN thread about it: https://news.ycombinator.com/item?id=36225016

Mold 2.0.0
I'm amazed at how quickly the author responds to requests: https://github.com/rui314/mold/issues/1057
From the report to the fix in less than two days.
I'm not sure how competitive it will be with lld, especially if we consider ThinLTO (which takes multiple minutes on 64-core machine) - it can make the advantages of mold insignificant.

Linking many files significantly increases build time. Is there an editor that allows you to write a single file but present the file to the screen as multiple 'virtual' files for better organization?
What other solutions have you tried for the problem of slow linking? You haven't even said which linker and what flags you're using. I haven't actually tried it, but the author of gold has an even faster linker called mold: https://github.com/rui314/mold

Before LLD?
What are some alternatives?
cargo-machete - Remove unused Rust dependencies with this one weird trick!
zld - A faster version of Apple's linker
bmrng - An async MPSC request-response channel for Tokio
wasmtime - A fast and secure runtime for WebAssembly
scip - SCIP Code Intelligence Protocol
osxcross - Mac OS X cross toolchain for Linux, FreeBSD, OpenBSD and Android (Termux)
arewefastyet - arewefastyet.rs - benchmarking the Rust compiler
zig - General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.
measureme - Support crate for rustc's self-profiling feature
chibicc - A small C compiler
cargo-dephell - Cargo dephell analyzes the third-party dependencies of a Rust workspace
sccache - Sccache is a ccache-like tool. It is used as a compiler wrapper and avoids compilation when possible. Sccache has the capability to utilize caching in remote storage environments, including various cloud storage options, or alternatively, in local storage.
