AFAIK, neither. Since slice API is pass-by-value, in theory ANY method will invalidate the pointer. In practice only resizing methods actually NEED to reallocate the underlying array, but magic can happen. However, refcounting will make sure that a previously underlying array having pointers to it will remain allocated. This means that 1. pointers to single elements will always dereference 2. slice structure modification can leave pointers pointing to stale data |
