| Type | Functionality | Moved-from State |
|---|---|---|
std::unique_ptr | Move construction, Move assignment "Converting" move construction, "Converting" move assignment (Likewise for std::unique_ptr for array objects with a runtime length) | The moved-from object is guaranteed to refer to a null pointer value, per [unique.ptr], paragraph 4 [ISO/IEC 14882-2014]. |
std::shared_ptr | Move construction, Move assignment | The moved-from object shall be "empty", per [util.smartptr.shared.const], paragraph 22 and [util.smartptr.shared.assign] paragraph 4. |
std::shared_ptr | Move construction and move assignment from a std::unique_ptr | The moved-from object is guaranteed to refer to a null pointer value, per [util.smartptr.shared.const], paragraph 29 and [util.smartptr.shared.assign] paragraph 6. |
std::weak_ptr | Move construction, Move Assignment "Converting" move construction, "Converting" move assignment | The moved-from object shall be "empty", per [util.smartptr.weak.const], paragraph 8, and [util.smartptr.weak.assign], paragraph 4. |
std::basic_ios | move() | The moved-from object is still left in an unspecified state, except that rdbuf() shall return the same value as it returned before the move, and tie() shall return 0, per [basic.ios.members], paragraph 20. |
std::basic_filebuf | Move constructor, Move assignment | The moved-from object is guaranteed to reference no file; other internal state is also affected, per [filebuf.cons], paragraphs 3 and 4, and [filebuf.assign], paragraph 1. |
std::thread | Move constructor, Move assignment | Calling The result from calling get_id() on the moved-from object is guaranteed to remain unchanged, but otherwise the object is in an unspecified state, per [thread.thread.constr], paragraph 11 and [thread.thread.assign], paragraph 2. |
std::unique_lock | Move constructor, Move assignment | The moved-from object is guaranteed to be in its default state, per [thread.lock.unique.cons], paragraphs 21 and 23. |
std::shared_lock | Move constructor, Move assignment | The moved-from object is guaranteed to be in its default state, per [thread.lock.shared.cons], paragraphs 21 and 23. |
std::promise | Move constructor, Move assignment | The moved-from object is guaranteed not to have any shared state, per [futures.promise], paragraphs 6 and 8. |
std::future | Move constructor, Move assignment | Calling valid() on the moved-from object is guaranteed to return false, per [futures.unique_future] paragraphs 8 and 11. |
std::shared_future | Move constructor, Move assignment "Converting" move constructor, "Converting" move assignment | Calling valid() on the moved-from object is guaranteed to return false, per [futures.shared_future] paragraphs 8 and 11. |
std::packaged_task | Move constructor, Move assignment | The moved-from object is guaranteed not to have any shared state, per [future.task.members], paragraphs 7 and 8. |
