Function std::intrinsics::volatile_copy_memory
pub unsafe extern "rust-intrinsic" fn volatile_copy_memory<T>( dst: *mut T, src: *const T, count: usize)
core_intrinsics
)intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library
Equivalent to the appropriate llvm.memmove.p0i8.0i8.*
intrinsic, with a size of count * size_of::<T>()
and an alignment of min_align_of::<T>()
The volatile parameter is set to true
, so it will not be optimized out unless size is equal to zero.
This intrinsic does not have a stable counterpart.
