Crate std_detect 

🔬This is a nightly-only experimental API. (stdarch_internal)

Run-time feature detection for the Rust standard library.

To detect whether a feature is enabled in the system running the binary use one of the appropriate macro for the target:

• x86 and x86_64: is_x86_feature_detected
• arm: is_arm_feature_detected
• aarch64: is_aarch64_feature_detected
• riscv: is_riscv_feature_detected
• mips: is_mips_feature_detected
• mips64: is_mips64_feature_detected
• powerpc: is_powerpc_feature_detected
• powerpc64: is_powerpc64_feature_detected
• loongarch: is_loongarch_feature_detected
• s390x: is_s390x_feature_detected
