Type lost when calling asyncIterator.call

[wong2]

I have the following code:

for await (const event of asyncIterator.call(eventStream)) {
  ...
}

Where eventStream is of type ReadableStream<ParsedEvent>, but the event is now unknown.

Thanks for reporting this issue. It's a TypeScript limitation that generics are lost in fn.call().

I refactored the asyncIterator ponyfill API in #30 to make it more functional.

Can you test it by installing the preview release package

npm i https://pkg.pr.new/@sec-ant/readable-stream@30

and change your code to this to check whether it fixes your problem?

for await (const event of asyncIterator(eventStream)) {
  ...
}

cc @ehmicky please be aware of this breaking change

Thanks, it works.
