yes it makes sense to use C/ASM here, but if you're curious, there is a rust port of dav1d named rav1d: https://github.com/memorysafety/rav1d
it's not much slower than the original C/ASM implementation (last i checked ~5%?) but that matters here
there's a rav2d now too fwiw — https://github.com/stukenov/rav2d same playbook: safe Rust + asm kernels via FFI. just shipped 0.1.0.
