Following up from an issue posted about in the community discord (link). It seems like ReadableStreams work well for byte arrays, but when trying to send Napi Rust Objects into the stream, nothing comes out in NodeJS.

I first experienced this when attempting to upgrade to napi-3.0 here: xmtp/libxmtp#2160 however was able to reproduce in my napi-rs fork with the stream tests here: https://github.com/insipx/napi-rs/blob/ee3d94c3b5e569c931f90298dfe11174eca889c7/examples/napi/src/stream.rs#L65

In this test, we are starting a tokio thread sending Foo into a receiver that is used to create the Napi ReadableStream type. The companion test in NodeJS for this is here

When running the NodeJS test, nothing gets sent to the stream

The working napi test is here. Difference being the 'create_with_stream_bytes' method is being used, and we do receive the bytes in NodeJS
