Function volatile_copy_nonoverlapping_memory

Source
pub unsafe fn volatile_copy_nonoverlapping_memory<T>(
    dst: *mut T,
    src: *const T,
    count: usize,
)
🔬This is a nightly-only experimental API. (core_intrinsics)
Expand description

Equivalent to the appropriate llvm.memcpy.p0i8.0i8.* intrinsic, with a size of count * size_of::<T>() and an alignment of min_align_of::<T>()

This intrinsic does not have a stable counterpart.

§Safety

The safety requirements are consistent with copy_nonoverlapping while the read and write behaviors are volatile, which means it will not be optimized out unless _count or size_of::<T>() is equal to zero.
