FYI, I forked and improved [1] a Rust implementation that supports both table- and SIMD-accelerated CRC-64/NVME [2] calculations. The SIMD-accelerated (x86/x86_64 and aarch64) version delivers 10X over the table (16-bytes at a time) implementation.

The original implementation [3] did the same thing but for CRC-64/XZ [4].
