Let the Compiler Do the Work

Clang also does some crazy-good SIMD optimizations if you set -march=native. But I think the Rust compiler is based on LLVM as well, right?

Everybody should build everything with a reasonable setting of march. Debian Linux still builds everything for K8, a microarchitecture that lacked SSE3, SSE4, AVX, AES, etc. Even building with march=sandybridge seems petty conservative and gives significant speed improvements in many common cases.
