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-bloat
- What's in a Rust binary?
-
Using Rust for kernel development
And, importantly, Rust has good tooling for finding out where bloat, if any, comes from, cargo-bloat
-
Compile time
You can run cargo bloat --time --release -j 1 (github) to see what dependency takes the most time and try to replace it. It would probably be some proc-macro monstrosity.
-
Profiling function size
I think you will be interested in cargo-bloat
-
Very fat binaries ?
Try to use this tool to get some insight. https://github.com/RazrFalcon/cargo-bloat

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.

Mold Course
I initially thought this would be about the mold linker (https://github.com/rui314/mold)

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 2.1.0 - rui314/mold
Loongson's LoongArch CPU has been supported. (03b1a1c)

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

Apple's new library format combines the best of dynamic and static
> Mold did it first, though: https://github.com/rui314/mold
Before LLD?
What are some alternatives?
resvg - An SVG rendering library.
zld - A faster version of Apple's linker
bevy - A refreshingly simple data-driven game engine built in Rust
wasmtime - A fast and secure runtime for WebAssembly
rust - Empowering everyone to build reliable and efficient software.
osxcross - Mac OS X cross toolchain for Linux, FreeBSD, OpenBSD and Android (Termux)
min-sized-rust - 🦀 How to minimize Rust binary size 📦
zig - General-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.
Warp - Warp is a modern, Rust-based terminal with AI built in so you and your team can build great software, faster.
chibicc - A small C compiler
shakmaty - A Rust library for chess and chess variant rules and operations
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.
