My string approach worked but was naive. Your enum-based design with TryFrom validation is the right way: type-safe, O(log n) lookups, feature alias support. Excellent work avx512: detect_avx512() && !disabled.contains(&"AVX512F".to_string()),
avx2: detect_avx2() && !disabled.contains(&"AVX2".to_string()),
pclmul: detect_pclmul() && !disabled.contains(&"PMULL".to_string()),
vmull: detect_vmull() && !disabled.contains(&"VMULL".to_string()),
sse2: detect_sse2() && !disabled.contains(&"SSE2".to_string()),
asimd: detect_asimd() && !disabled.contains(&"ASIMD".to_string()), |
