| //! 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`] |
