Crate target_features 

Types and constants for working with target features.

Target feature constants are provided in a module named for the target architecture, such as x86_64 or aarch64. Each constant includes the target feature it names and any implicitly enabled target features.

use target_features::{TargetFeatures, x86_64::{AVX, BMI2, FMA}};

const REQUIRED: TargetFeatures = AVX.with(FMA).with(BMI2);
assert!(REQUIRED.contains(AVX));
