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.

Bugs Rust Won't Catch
To be fair, Vec::set_len bug in Rust was in 2021. And even then it had to be annotated as `unsafe`. It was then deprecated and a linter check was added: https://github.com/rust-lang/rust-clippy/issues/7681

Debloat Your Async Rust
It's interesting that you can remove a constant state machines by just returning impl Future with return std::future::ready(return_value). They even developed a lint[1] to tell users about it. https://github.com/rust-lang/rust-clippy/pull/16244
Could the compiler not identify this case and perform the transformation automatically?

Why We Chose Rust For Spin
cargo, rustfmt, clippy, rust-analyzer, and Rust’s robust unit testing capabilities together form a powerful ecosystem for managing large-scale projects like Spin.

Automated Testing and Dev Containers
Firstly, I added a section to run the code formatter rustfmt and the linter clippy:

More than you've ever wanted to know about errors in Rust
I couldn't find it in the API guidelines either. From what I understand, the idea is that any trait bounds, which includes generic type parameter bounds and lifetime bound on a type (struct or enum) would be repeated back in the impl block
there is a nice discussion on this issue here: https://github.com/rust-lang/rust-clippy/issues/1689

New clippy lint: detecting `&mut` which could be `&` in function arguments
You should not blindly follow clippy lints. They are sometimes wrong. Another example https://github.com/rust-lang/rust-clippy/issues/9782 .
- Let else will finally be formatted by rustfmt soon
-
My deduplication solution written in Rust beats everything else: casync, borg...
I often write () = f() to assert that f() is unit. Unfortunately clippy warns on such code ( https://github.com/rust-lang/rust-clippy/issues/9048 ). There are very recent pull requests for this bug, so hopefully this bug will be fixed very soon. But meanwhile I invented this workaround: [()] = [f()] :)

Any open source projects willing to take in juniors?
Apart from running clippy on many projects being essential, clippy is also an exceptionally welcoming project, no matter your prior knowledge.

Any new Opensource projects in (rust) looking for contributors. I want to start my journey as an OSS contributor.
clippy is a great place to get started :) though it isn't exactly new.

Mun v0.4.0 released
For those of you who haven’t heard of Mun before, Mun is an embeddable programming language empowering creation through iteration. The idea to create Mun originated out of frustration with the Lua dynamic scripting language and a desire to have similar hot reloading functionality available in Rust. As such, it’s not a direct competitor with Rust, but instead is intended to be used with Rust (or C/C++) as a host/embedded language pairing. Actually, Mun is completely written in Rust, building on similar crates as rust-analyzer and rustc. Its key features include:
-
rust-analyzer changelog #159
#13728 upgrade chalk to make solver fuel work again (works around most trait solving hangs).

#13221 (first contribution) add option to move lenses above doc comments (rust-analyzer.lens.location):
