static osmid_t pop_id(pending_queue_t &queue, std::mutex &mutex)
{
osmid_t id = 0;
std::lock_guard<std::mutex> const lock{mutex};
if (!queue.empty()) {
- id = queue.top();
- queue.pop();
+ id = queue.back();
+ queue.pop_back();
`stack::top()` calls the underlying containers `back()` function, and `pop()` calls `pop_back()`. So I believe we are doing exactly the same here.
