//! 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`]
