I have a problem where if I use my class as the element type in a vector it doesn't move it but rather constructs it and tries to copy assign it (I believe because the compiler sees certain functions as throwing exceptions). I don't want to redefine my own move constructor every time this happens, can I default the move constructor but specify that it's noexcept?

struct QueueSubmission
{
    QueueSubmission(VulkanFence is_completed_fence) : is_completed_fence(is_completed_fence)
    {}
    QueueSubmission(QueueSubmission&& other) noexcept = default; 
    QueueSubmission& operator=(QueueSubmission&& other) noexcept = default;
/* CommandBufferUniquePointer cannot be copied, but only moved */   
std::vector<CommandBufferUniquePointer> command_buffers_submitted;

};

CodePudding user response：

Yes, if functions are defaulted on their first declaration without noexcept specifier, then they will be noexcept(true) if and only if they don't contain anything potentially throwing.

But if you add a noexcept specifier this will override it.

Note my comments under your question though.
