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.

Cranelift code generation comes to Rust
Windows is supported. See https://github.com/rust-lang/rustc_codegen_cranelift/issues/....
- What part of Rust compilation is the bottleneck?

A Guide to Undefined Behavior in C and C++
> When this happens, it seems like it'll be possible to get the LLVM bits out of the bootstrap process and lead to a fully self-hosted Rust.
What do you mean by "when this happens"? GP's point is that this has already happened: the Cranelift backend is feature-complete from the perspective of the language [0], except for inline assembly and unwinding on panic. It was merged into the upstream compiler in 2020 [1], and a compiler built with only the Cranelift backend is perfectly capable of building another compiler. LLVM hasn't been a necessary component of the Rust compiler for quite some time.

What are some stuff that Rust isn't good at?
Note that the Cranelift codegen will eventually become standard for debug builds to speed them up.
-
Rust port of B3 from WebKit, LLVM-like backend
Maybe one day we'll have rustc b3 backend like what they did with Cranelift
-
Any alternate Rust compilers?
Additionally, there is gcc codegen for rustc (https://github.com/rust-lang/rustc_codegen_gcc), which is not a compiler per se, but an alternative code generator, with more architectures supported and other nice things. It's also coming along, but there's still a lot of work to do there too. There's also Cranelift codegen (https://github.com/bjorn3/rustc_codegen_cranelift), which is designed to make debug builds faster, but this is not as exciting/useful as the other 2.

Capsules, reactive state, and HSR: Perseus v0.4.0 goes stable!
For the instant reloading, that's in Sycamore, so you should speak to its devs, but as for the alternative compiler backend, it's not my project, but it uses Cranelift and works pretty well! See https://github.com/bjorn3/rustc_codegen_cranelift for details.
- Security Engineer looking for ways to see if any of my tasks could slowly be ported to Rust or should I just stick with Python.
- Rust is now officially supported on some Infineon microcontrollers! (more to come later this year)
-
Improving Rust compile times to enable adoption of memory safety
The more immediate goal of "distribute the cranelift backend as a rustup component" has been making good progress and seems like it might happen relatively soon https://github.com/bjorn3/rustc_codegen_cranelift/milestone/...

OpenBSD 7.5 Released
It would be great for Rust to have a Linux target that doesn't use libc, but from what I've read, not many people are interested in this.
Found this as well: https://github.com/sunfishcode/mustang
Some discussion here: https://github.com/bytecodealliance/rustix/issues/76

Rust criticism from a Rustacean
On Linux there has been some attempts to get exactly this solutions, most notibly https://github.com/sunfishcode/mustang but the topic did not seem to fetch a prominent position on the supported feature list.
-
Microsoft rewriting core Windows libraries in Rust
For Linux, Mustang already exists because Linux has a stable syscall API
- Mustang: Rust target with std and no linking to a Libc
-
The Rust Implementation Of GNU Coreutils Is Becoming Remarkably Robust
Why bother with a libc at all, when you can skip it entirely on Linux!
-
Why so few, if any, pure Rust apps?
Mustang is a project which is able to run some non-trivial programs written in Rust, such as ripgrep, without using any libc, on Linux.
-
Can rust be entirely written in rust and drop C usage in its code base ?
Mustang is one way to take care of the tiny amount of "C" that runs before main().
-
How do I use Zig as Rust's Standard C Library?
This is more a Rust question than a Zig question. In Rust, the choice of a specific libc (or to not use a libc) is part of the "target", for example many hardware platforms have gnu/musl/none targets. See also relibc or mustang for pure-rust alternatives. Each libc alternative require some work to integrate into Rust.
-
memmapix: A pure Rust library for cross-platform memory mapped IO, which replace libc with rustix.
There's a separate project for that, called Mustang. It's built on top of rustix and provides all those things. It's not super mature yet, but it is able to run ripgrep by itself: https://github.com/sunfishcode/mustang
What are some alternatives?
wasmtime - A fast and secure runtime for WebAssembly
ziglibc
gccrs - GCC Front-End for Rust
relibc - Mirror of https://gitlab.redox-os.org/redox-os/relibc
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.
