Transferable support #51
Description
Hi!
Do you think you could include a way to pass Transferable objects correctly?
It would be great to be able to return a MessagePort so that the function can return a stream instead of a single value.

Absolutely! We added it to greenlet in only a few bytes, the same solution should work reasonably well here. It would only auto-detect transferables passed directly as arguments, not within nested objects:

Hi I'm a bit late to the party but it seems unclear to me... Are transferable objects supported by
workerizeor not?developit commentedon May 7, 2020
They are not currently supported.

May I ask why only direct arguments? Why not detecting ArrayBuffers nested inside an object or an array?

I was thinking of a way to specify a loader option for how to extract the transferable from the arguments and return value of a worker method, but I realized that it would be impossible to determine the best option for each worker method with just one loader option. Instead, the approach I took was to call setup functions on both the worker and the main thread side to determine how to extract the transferables for each worker method. I've made a helper module to achieve this.
