:mrdocs:

Add the specified `functor` at the front of the queue specified by `id`. Return 0 if added successfully, and a non‐zero value if queuing is disabled. If passed by movable reference, the value of `functor` becomes unspecified but valid, and its allocator remains unchanged. The behavior is undefined unless `functor` is bound. Note that the position of `functor` relative to any currently queued jobs is unspecified unless the queue is currently paused.
