Queue is a thread-safe FIFO queue implementation.

func NewQueue[T types.Marshallable]() *Queue[T]

NewQueue creates a new Queue instance.

func (q *Queue[T]) Delete(string) error

Delete is no-op for the in-memory queue (already deleted by receiving).

func (q *Queue[T]) Len() int

Len returns the number of elements currently in the queue.

func (q *Queue[T]) Push(val T) (string, error)

Push adds a value to the back of the queue.

func (q *Queue[T]) Receive() (string, T, bool)

Pop returns the value at the front of the queue without removing it. The second return value indicates if the operation succeeded.

func (q *Queue[T]) ReceiveMany(num int32) ([]string, []T, error)
