The trait for derive-c allocators. Behaviour is more restrictive that the standard allocator, and provides additional information.

  • The user is trusted to store, or correctly infer (e.g. via types) the size of the allocation

Additiona poisoning is done.

  • For msan, we set bytes removed by reallocating smaller. (not done by normal allocator, and The behaviour is stricter than the malloc/calloc/realloc/free:
  • Throws on allocating zero sized
  • Never returns null pointers from realloc, malloc, calloc
  • Throws on freeing a nullptr
  • Throws on reallocating to zero size
