stream chain should allow non-standard WebStream?

[himself65]

I have a custom class that implement AsyncIterator protocol but in this library, it will throw error

Could you elaborate on that, preferably with code examples?

Thanks for following up.

Here is my implementation, https://github.com/run-llama/llama-flow/blob/68f3c4e81ce605feb6615dfade33a84ce0f0a2a9/packages/core/src/core/stream.ts

First of all: I am not happy at all to support non-standard streams. Why didn't you implement a custom stream using standard ReadableStream API? What was wrong defining it in terms of start(), pull(), cancel() as documented in ReadableStream constructor? What were your compelling reasons for that? I would like to hear them before making the decision.

The next version of stream-chain (4.x) will be based solely on standard web streams and it will break your code. Just a fair warning.
