queue

问题 The Dart core API has two classes that implement the Queue<E> interface, DoubleLinkedQueue<E> and ListQueue<E>. The documentation of both classes is almost identical, the only difference that is explicitly mentioned is the following note in the ListQueue<E> documentation: Operations like removeAll and removeWhere are very inefficient. If those are needed, use a DoubleLinkedQueue instead. What is the actual difference between them implementation-wise and when should which implementation be

问题 I'm having issue with checking if my circular queue is full or not. The maximum size for the queue is set to 5. However, after putting in 4 elements, it doesn't let me add a fifth element. I'm stuck. Console output void init (struct data* ptr) { ptr->rear = 0; ptr->front = 0; } void display (struct data* ptr) { if (empty(ptr)) { printf("\nNo data to display. The queue is EMPTY.\n"); } else if (ptr->rear > ptr->front) { for (int i = ptr->front; i < ptr->rear; i++) { printf ("%d ", ptr->data[i]

问题 Hope you guys are doing great. I implemented BullMQ (next major version of Bull) into my nodejs project to schedule the jobs to send emails. For example, send email of forget password request. So, I have written my code something like below. User Service: await resetPasswordJob({email: 'xyz@test.com'}); // from service I'm calling a job Reset Password Job: const {Queue} = require('bullmq'); const IOredis = require('ioredis'); const connection = new IOredis(process.env.REDIS_PORT || 6379);

问题 I'm trying to consume from a child process a synchronized queue in c++. I'm using this synchronized queue in C++ () (http://www.internetmosquito.com/2011/04/making-thread-safe-queue-in-c-i.html) I modified the queue to be serializable in boost and also replaced the used boost::mutex io_mutex_ to use instead an inteprocess mutex (thanks @Sehe) boost::interprocess::interprocess_mutex io_mutex_ And when locking I changed every line that has boost::mutex::scoped_lock lock(io_mutex_); to scoped
