std::experimental::unique_resource<R, D>::operator=

unique_resource& operator= ( unique_resource&& other ) noexcept ( /*see below*/ ) ;		(library fundamentals TS v3)

Move assignment operator. Replaces the managed resource and the deleter with other's.

Formally, let RS be the type of stored resource handle:

• First, calls reset() to dispose the currently owned resource, if any.
• Then assigns the stored resource handle and the deleter with other's. std::move is applied to the stored resource handle or the deleter of other if std::is_nothrow_move_assignable_v<RS> or std::is_nothrow_move_assignable_v<D> is true respectively. Assignment of the stored resource handle is executed first, unless std::is_nothrow_move_assignable_v<D> is false and std::is_nothrow_move_assignable_v<RS> is true
• Finally, sets *this to own the resource if and only if other owned it before assignment, and other

If std::is_nothrow_move_assignable_v<RS> is true, RS shall satisfy the MoveAssignable requirements; otherwise RS shall satisfy the CopyAssignable requirements. If std::is_nothrow_move_assignable_v<D> is true, D shall satisfy the MoveAssignable requirements; otherwise D shall satisfy the CopyAssignable

Parameters

other

-

resource wrapper from which ownership will be transferred

Return value

*this

Exceptions

Any exception thrown in copy-assignment.

Notes

If a copy of a member throws an exception, this mechanism leaves other intact and *this
