TaskQueue
A ruby implementation of a simple dispatch queue using procs
Currently, TaskQueue only has api for dispatching tasks asynchronously.
Example
# Create a queue with as many workers as you want or 1 for a serial queue
queue = TaskQueue.new(name: 'my concurrent queue', number_of_workers: 5)
task = Task.new(work_block: proc {
# some work to be done
})
queue.add_task_async(task: task)# Or don't supply the number of workers and you'll only get 1, making it a serial queue
queue = TaskQueue.new(name: 'my serial queue')
task = Task.new(work_block: proc {
# some work to be done
})
queue.add_task_async(task: task)Recreatable Tasks
The tasks that are created from the mixin RecreatableTask can be recovered in future executions of the TaskQueue where their were enqueued originally.
Example
# We define a task that includes RecreatableTask
class HelloToRecreatableTask
include TaskQueue::RecreatableTask
# The run! method receives a collection of params and defines the real execution of the task itself.
def run!(**params)
puts "Hello #{params}"
end
# In case the queue gets deallocated with RecreatableTasks on its queue, the hash returned by this function will be stored. Make sure that all values are JSON encodable.
def params_to_hash
{ to: "fastlane" }
end
end
queue = TaskQueue(name: 'test queue')
task = HelloToRecreatableTask.new.to_task
queue.add_task_async(task: task)Run tests
