dynamically-sized text object with a copy constructor, a trivial assignment operator, and a trivial destructor

Question

I\'ve been shown that a std::string cannot be inserted into a boost::lockfree::queue.

boost::lockfree::queue is too valuable to ab

Answer 1

A dynamically-size type with a trivial copy ctor/dtor is not possible. There are two solutions to your problem, use a fixed sized type, or store pointers in the queue:

boost::lockfree::queue queue(some_size);
// push on via new
queue.push(new std::string("blah"));
// pop and delete
std::string* ptr;
if(queue.pop(ptr))
{
   delete ptr;
}
