Error handling in read function

[pantelis-karamolegkos]

Not an issue but rather a question:

How any other error besides io.EOF would be handled here?

Thanks.

Hello!

Great question and also it looks like I totally forgot to check other errors, thanks for calling that out.

I approach this in two different ways:

• Return another channel for the error and use select together with the one for reading the values (errGroupWithErrChannel)
• Define a new type that saves the err value and check that after the reading channel is closed (errGroupWithType)

Both implementations are here; to keep everything simple I'm only showing the example using errgroup, but using sync should be similar.

I typically start with the function and then depending if I need more details about the read process I implement the type one.

I hope that helps.
