Sharpview, my metaverse viewer: 36,000 lines, 0 are unsafe. I use some published crates that have unsafe code, but my own programs start with #![forbid(unsafe_code)]
This is 60FPS 3D high-detail graphics stuff, where performance matters. |

Other libraries like Vulkan and DirectX 12 are fundamentally unsafe in the API level, so direct usage of it would lead to heaps of unsafe Rust code. Rust people have tried wrapping it in a safe way (like gfx-rs and vulkano) but nowadays most seem to have transitioned to wgpu (since WebGPU API is safe by design so it fits more for the Rust ecosystem).
Rust does sacrifice some performance in general in order to achieve its safety claims, but people are happy with it so far, since the majority of applications using Rust (like CLI apps and web servers) don't have to squeeze out performance that much (for webdev there are too many things that can cause performance issues other than not writing it in Rust). But for 3D graphics people can be more sensitive about these problems. Though maybe if you're not developing a triple-A game with the latest cutting-edge graphics (with new techniques like "hardware ray tracing" and "bindless descriptors", which are both impossible in wgpu), writing in Rust can be a good-enough tradeoff for your needs.
