WebWe can launch some async IO and send the results into an event queue which Brick reads from. But it is really annoying: The update function must know which async resources to load, duplicating parts of the rendering logic The update function must track which resources are already loaded WebAsync is a futures library, and io-streams is a streaming library. Focus on a small and simple API with lots of expressiveness and obviously correct constructions. Can call wait or poll on Asyncs. io-streams have …
