Shorthand for pcall.
Run body with a fresh thread pool. If on-unwind is :wait, it will wait for all tasks to finish before returning. If it is :leave, the form will return while threads are still working. If it is :stop or :destroy, the threads will be stopped at the end of the body. With :stop, they will first finish their current task (if any), with :destroy, they will be brutally destroyed and might leak resources, leave stuff in inconsistent state, etc.
Join a task, meaning stop execution of the current thread until the result of the task is available, and then return this result. When this is called on a task that no thread is currently working on, the current thread executes the task directly.
Create an empty queue.
Call a thunk in parallel. Returns a task that can be joined. When an exclusive is given, the task will only run when no other tasks with that exclusive are running.
Test whether a queue is empty.
Find the length of a queue.
Pop an element from the front of a queue. Returns immediately, returning nil if the queue is empty, and a second value indicating whether anything was popped.
Push an element onto the back of a queue.
Pop an element from the front of a queue. Causes a blocking wait when no elements are available.
Returns the first task that can be joined without blocking.
Make sure the thread pool holds the correct amount of live threads.
Execute a task, and store the result or error in the task object. When a task’s status is not :free, that means the joiner has already started executing it, so this thread should leave it alone.
next.
prev.
The code running inside the pooled threads. Repeatedly tries to take a task from the queue, and handles it.
