unsafe in user code

[kirillsurkov]

Hello! I recently started learning Rust. As the start point I chose some simple 3D application, and after a while I found this library.
I'm a little bit confused about using unsafe in user code. E.g. this example: https://github.com/gfx-rs/wgpu/blob/master/wgpu/examples/hello-triangle/main.rs#L11

Isn't it possible to avoid those unsafes in user code? Is it language limitation or library imperfection?

Thank you!

wgpu is still quite low-level, so not everything is safe. In this case it's because wgpu doesn't handle the actual window creation, and so it's relying on you to do that correctly and pass a valid window handle. Passing an invalid window handle could result in UB.

If you want a higher-level library which handles things like window setup automatically, you might try bevy.
