Fast bitset decoding using Intel AVX-512
https://developer.arm.com/documentation/ddi0596/2020-12/SIMD...
I believe it does 128 bits per instruction, but I'm still struggling with rust w/ asm.
Along my journeys, however, I found this repo https://github.com/WojciechMula/sse-popcount/ which has tons of competing simd implementations for both intel and arm.

Counting set bits in an interesting way
The builtin POPCNT that came with Intel's SSE4 (SSE4a for AMD) is much faster. However, at a certain point, using AVX2 (and AVX-512 if present) is actually faster yet [1] - at least for 512 byte inputs or larger.
