Function arrow::memory::memcpy

pub unsafe fn memcpy(dst: NonNull<u8>, src: NonNull<u8>, count: usize)

Safety

Behavior is undefined if any of the following conditions are violated:

• src must be valid for reads of len * size_of::<u8>() bytes.

• dst must be valid for writes of len * size_of::<u8>() bytes.

• Both src and dst must be properly aligned.

memcpy creates a bitwise copy of T, regardless of whether T is Copy. If T is not Copy, using both the values in the region beginning at *src and the region beginning at *dst can [violate memory safety][read-ownership].
