Function copy_vec_ptr

src/util/low_level.rs:9–17

Copy each value from `src` through the corresponding pointer in `dst`. # Safety `dst` and `src` must have equal length (enforced by debug assert). Every pointer in `dst` must be valid for writes of `T` and properly aligned. Aliased pointers within `dst` produce undefined behaviour. No concurrent reader may access the locations written through `dst`.
