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.
