jni-rs VS windows-rs

I do have education and real experience in the field. See, for example, my recent work on the rather arcane subject of Rust↔Java FFI. You don't get to pull rank with me, son. I know quite well what CreateFile does. (Fun fact: it creates a file handle, i.e. opens a file, and may or may not create the file itself.)

I've been playing around with jni-rs, I'm eventually planning on developing an app with Java gui and Rust backend. However I'm having some trouble advancing past HelloWorld lol. For example, here's some simple code that doesn't work and I really can't figure out why:

- JNI - how well does https://github.com/jni-rs/jni-rs work? Assuming that Firefox runs on Android and uses Rust this should be reasonable to work with?

Even so, staying relatively close to the Java focus of the class might be a good idea, since it will help prepare you for the AP exam. One idea would be using jni-rs to build Java bindings for a useful Rust library. Interesting candidates might be io-uring, lockfree, or even pyo3, if you wanted to try your hand at integrating Java and Python.

I'd say Rust does have that big ticket ecosystem push. Microsoft has been embracing Rust lately, with things like official Windows bindings [1].

The bigger problem is just inertia: large game engines are enormous.

It's a shame that, unlike with Win32, using WinUI places pretty harsh restrictions on which programming languages and environments you can use. Only C# and C++ are supported, the latter only with Microsoft compilers. For everything else, including Rust[1], Python and MinGW C/C++, there is no answer for OP's question, and the effect of this on the visual consistency of the Windows desktop is obvious - there is none. Every third-party app uses a different toolkit with a different look and feel, because the library providing the standard look and feel simply isn't available to the majority of developers.

On Windows you'd need to call the LoadLibraryEx method. You'd also need a crate to call Win32 functions, I suggest windows-rs.

windows-rs, Microsoft's crate wrapping the Windows API, already includes the WDK, the special sdk for creating kernel code.

On windows, I'll probably use https://github.com/gabdube/native-windows-gui or https://github.com/microsoft/windows-rs both of them seem pretty solid.

*nod* It's an official Microsoft thing generated from official Microsoft API definition files. (The repo is at microsoft/windows-rs on GitHub.)

Microsoft offers official "bindings" to Win32 APIs through win32metadata. However, until recently, it did not include metadata for kernel-level functions or WDK. In early 2021, an issue was raised through windows-rs regarding this limitation, but progress was slow until now. Microsoft has finally released official metadata for WDK, which can be found on the wdkmetadata repository. The latest comment on the issue thread can be found here:

Is something wrong with https://github.com/deviceplug/btleplug or you haven't found it? You could also use bindings to platform libraries like https://github.com/microsoft/windows-rs and https://github.com/rust-mobile/ndk if btleplug doesn't have something fundamental to you.
