Function std::intrinsics::volatile_store

pub unsafe extern "rust-intrinsic" fn volatile_store<T>(dst: *mut T, val: T)

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

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

对 dst 指针执行易失性存储。

这个 intrinsic 的稳定版本是 core::ptr::write_volatile。
