The pattern provides a safe abstraction for runtime CPU detection and SIMD dispatch. It's gnarly AF, but Fearless SIMD 1.0 came out a few days ago so people won't have to implement it themselves anymore.
I'd recommend grabbing that lib and giving SIMD-in-Rust another shot.
NGL, SIMD in Rust has not been a great experience. Philbin uses the "CPU Feature Tokens" pattern that the Fearless SIMD team (which the root article's author is a part of) came up with: https://shnatsel.medium.com/safe-simd-in-rust-even-on-the-in...
