> At the same time, work towards WASI 0.3, also known as WASI Preview 3, will be getting underway. The major banner of WASI 0.3 is async, and adding the future and stream types to Wit. And here again, the theme is composability. It’s one thing to do async, it’s another to do composable async, where two components that are async can be composed together without either event loop having to be nested inside the other. Designing an async system flexible enough for Rust, C#, JavaScript, Go, and many others, which all have their own perspectives on async, will take some time, so while the design work is starting now, WASI 0.3 is expected to be at least a year away.
