pub unsafe extern "rust-intrinsic" 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>()
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.
