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.

Improving Interoperability Between Rust and C++
Vtables are pretty solved as well. I do a lot of Windows COM interop. Using the `windows` crate, vtables for COM interfaces are relegated to an implementation detail - instead you simply implement a (typically safe!) trait:
https://microsoft.github.io/windows-docs-rs/doc/windows/Win3...
Which can then be converted to a refcounted smart pointer:
https://microsoft.github.io/windows-docs-rs/doc/windows/Win3...
All driven by win32 sdk parsing and metadata.
But suppose we want to roll our own, because we tend to prefer `winapi` but it lacks definition. That's not too terrible either:
• https://github.com/MaulingMonkey/thindx-xaudio2/blob/master/...
• https://github.com/MaulingMonkey/thindx-xaudio2/blob/master/...
• https://github.com/MaulingMonkey/thindx-xaudio2/blob/master/...
I could more heavily lean on my macros ala `windows`, but I went the route of manual control for better doc comments, more explicit control of thread safety traits to match the existing C++ codebase, etc.
Is there some pointer casting? Yes. Is it annoying or likely to be what breaks? No. What is annoying?
• Stacked borrows and narrowing spatial provenance ( https://github.com/retep998/winapi-rs/issues/1025 - this can be "solved" by sticking to pointers ala `windows`, or by choosing a different provenance model like rustc might be doing?)
• Guarding against panics unwinding over an FFI boundary. This is at least being worked on, but remains unfinished ( https://rust-lang.github.io/rfcs/2945-c-unwind-abi.html )
• Edge case ABI weirdness specific to C++ methods ( https://devblogs.microsoft.com/oldnewthing/20220113-00/?p=10... , https://github.com/retep998/winapi-rs/issues/523 )

Trying to compile rust library on Windows
Is winapi = { version = "0.3.9", features = ["winuser"] } in [target.'cfg(windows)'.dependencies]? All the missing symbols are functions in module winapi::um::wincrypt (see https://docs.rs/winapi/0.3.9/winapi/um/wincrypt/index.html#functions ) and the crate's Git repo at https://github.com/retep998/winapi-rs contains all the import libs and export defs for the corresponding DLLs in directory x86_64. As crypt32.dll ships with windows by default, I think this is all that would be needed for building on a windows PC.

I seen people say that () is similar to void in C. But what is similar to void*?
The std library provides the type c_void for FFI, which is an enum with two variants. Some libraries have their own version, winapi for example defines c_void as an enum with no variants, making it identical to !. Finally, whenever the std needs a pointer with no particular type, they tend to reach for *const (), see ptr::to_raw_parts.

Kernel Headers for Windows could soon make it into windows-rs
This would be a community driven project for now but I have high hopes considering we already had projects like winapi and Trantect/winapi-rs.

More malware is shifting to Rust
Can't you choose to control what OS APIs you use if you use crates such as libc and winapi, or just directly using extern "C" { ... }/extern "system" { ... }, or even inline assembly for syscalls with llvm_asm! or asm!?
- Noob question - Can I see what my used cargo crate has inside?

Building Outer Wonders, our Rust/SDL2 puzzle game, for Windows
Thank you! For SDL2 access, we're using custom bindings over the sdl2-sys crate, along with custom bindings for OpenGL and Vulkan access, and the winapi crate for Direct3D 11 access (as well as access to a few Windows APIs).

Hey Rustaceans! Got an easy question? Ask here (23/2021)!
What is the difference between the winapi crate and the windows crate? Are they the same thing, and is one better than the other?

The playable demo of Outer Wonders, our cute, colorful and Rust-powered puzzle game, is live on itch.io for Windows and Linux! Thank you Rust community for creating such awesome tools!
Turns out OpenGL and Vulkan sometimes behave weirdly on Windows machines (some OpenGL drivers use a huge amount of CPU power and create unexpected sync points; I also ran into this very weird driver crash while testing our Vulkan-powered version of Outer Wonders which is scary), so we implemented Direct3D 11 support using the winapi crate, which was much of a relief (D3D11 is an ideal rendering API when it comes to supporting Windows because it allows you target hardware with Windows versions going as far back as Vista, and from my experience, Direct3D drivers have a more consistent and reliable behavior). We didn't have to bring significant changes to our abstraction layer to add Direct3D 11 support.

Is statically compiling against glibc possible?
To compile a program with musl on a glibc system you can use cross-rs!

If docker is available for you, https://github.com/cross-rs/cross is another and reliable way to solve this kind of problem. I do use it regularly.

A guide to cross-compilation in Rust
There is some built-in support in rustc for cross-compiling, but getting the build to actually work can be tricky due to the need for an appropriate linker. Instead, we’re going to use the Cross crate, which used to be maintained by the Rust Embedded Working Group Tools group.
-
Is there a definitive guide on cross-compiling with OpenSSL?
I have used cross before to cross compile from Linux to other Linux. It has a section on it's wiki about this. Maybe that could be of help.

Docker ARMv7 Alpine Rust builder
You can use cross to build your application and copy the artifacts into an alpine armv7 container. It would also build faster due to using cross compilation rather than QEMU.

Compiling Linux to Mac in CI/CD
Looks like cross is the easiest way to get something cross-compiled but its Mac support is blocked behind building your own build image. Even that repo says that it might be broken.

How to you develop in containers?
Bonus: if you’re working with Rust and doing a lot of cross platform stuff, check out cross. It runs QEMU in docker so you can run tests on a bunch of different emulated targets easily- literally a one line setup, it’s kind of magical.

What are some stuff that Rust isn't good at?
It's also not as naturally cross-compilable as Go, though that's partly a side-effect of not accepting being a semi-closed ecosystem to achieve that and cross exists as a stop-gap while things like cargo-zigbuild explore less drastic options.
