Support async_sequence - #2533
Conversation
|
Please just do the async_sequence part, the other parts are too big to consume. |
Sure, but how can we test it without upgrading the library? |
|
That's a good question. But it's kinda more important to make the job pass than making it correct right now, we'll get it checked later when we get the actual IDL updated. |

Done. Thanks for looking at this. When will you check my previous PRs? Or should I close them? |

What is main & fallback builds? Can we say legacy TS versions?

Why?

forwards-compatible?

I don't think we care about TS < 2.3, minimum supported version is already 4.4.
That said, AsyncIterable does require separate asynciterable.d.ts until TS 6.0, so to make it correct we need to defer any functions that uses async_sequence to asynciterable variant.
Given we don't really test it here, it's also acceptable to just entirely skip the generation for those functions with some console warning.

I don't think we are doing this?

I don't quite understand this comment but i have pushed a change tell me if this is what you mean

Let it just empty as others did here
