Web Worker library

[fitzgen]

• Spawning web workers
• Communicating via postMessage

this is for when we are not using shared memory and multithreading

Why not both?

Why not both?

Ah, yeah it is true that it could work in either situation. I expect that using a custom channel based on shared memory will be much faster than postMessage when multithreading is available but there is no technical reason why you couldn't still use postMessage. Although, the receiver thread would have to return the to event loop to be woken up by the postMessage...

I think basic the implementation would like this:

struct Worker<T> {
     raw: web_sys::Worker
     _data: PhantomData<T> 
};

impl<T> Worker {
    fn new(path: impl AsRef<str>) -> Self {
        let worker = web_sys::Worker::new(path)
        Self { worker, _data: PhantomData }
    }

    fn split(self) -> (Sender<T>, Reciever<T>) { ... }
}

impl<T> Stream for Worker<T> { ...  }

impl<T> Sink for Worker<T> { ...  }

This would of course be based on futures. Once this basic implementation is in place, all the bells and whistles (if needed) could be added later.
