For anyone who is confused: This is exploiting an old soundness bug in the Rust compiler that is still present. The GitHub issue page has this comment from maintainers:
we already had a crate published on crates.io before which used this bug to transmute in safe code, see #25860 (comment).
this issue is a priority to fix for the types team and has been so for years now. there is a reason for why it is not yet fixed. fixing it relies on where-bounds on binders which are blocked on the next-generation trait solver. we are actively working on this and cannot fix the unsoundness before it’s done.

Like a lot of graphics programmers, I fell into the rabbit hole of rendering fractals. However, I never stopped - over the past couple of years I have slowly been building one of the most sophisticated Mandelbrot/Julia rendering programs that I am aware of. It has a mostly intuitive user interface, and does all of the calculations on the GPU. It has to use a bunch of mathematical tricks to get around the limits of single-point precision available in shaders. Because of the GPU rendering algorithm, I’ve managed to view fractal locations at around 10^250 times magnification with near real-time performance.
I also built a really in-depth compositing/coloring system, allowing you to make some really crazy images and get a lot of variation even for the same location:
Although it has only been me working on it, I think it is in a pretty mature state so far, and I would gladly take PRs/issues if anyone happens to be interested. It should support any OS if you compile it from source, but I don’t have binary releases set up yet.
