question: do we need pointer semantics here (and in the constructors)?

if you notice the changes on sender
file require a pointer since the library used assumes that if nil is passed default is assumed. If in the future the library does the same for the receiver it will be prepared to it. WDYT?

That is fine, you can always use the copied value with &var
- but make a copy of the provided struct (to avoid races/bugs) when calling New...()

sure, gone back to not using pointer for this case
@embano1 actually it was not supposed to be done. I was thinking of upgrading it all but there is no need and required more changes. |
Thx, I still see the bumps though? |
@embano1 I actually upgraded to 1.21 since its the version referred on build steps and others. do you see any issue in doing so? |
IMHO we want to keep

understood, you are absolutely right! reverted it all to 1.18 again! thanks |

would be much nicer if those would not be pointers IMHO

the thing here is that internally there is a default behavior assumed for a nil passing. from there I am assuming a pointer here. is it wrong?

The Receiver
does not use this though (uses struct semantics). Is this expected? If passing nil
is valid we
- either need to document this or

interesting: so we don't need those options, which goes back to my comment on keeping functional options pattern

in the other function you used structs on return
any change that this will be merged soon? using the stable go-amqp version would be nice. |
@cx-joses are you still down to finish this one? |
I am, I had vacations and another internal topics that made this pending but I will pick it up. Thanks for the notice! |
@cx-joses not to put pressure on you :-) but this was identified as one of the ones we'd like to get merged before we cut a new release...soon-ish. If you don't think you'll have time to rebase and address Michael's comments soon please let us know |
@duglin what is the timeline you guys are expecting? sorry for the lack of time on this, this is a priority for me also but came in a difficult time! Let's see if I find the time tomorrow to work on this |
@cx-joses I don't think there's a firm date, just people getting antsy because of all of the new stuff that's gone in and in particular the release of the CESQL v1.0 spec - which the SDK now supports. |

Can you please explain why we need WithReceiverOpts and WithReceiveOpts (also for send)? Is there a way to only have one? These changes complicate the API and I'm having a hard time understanding why we need those very similar options (and I guess new CE users would also be slightly confused?)

IIUC, this is for the sender/receiver construction, which currently does not support options. Do we need this new functionality at the cost of a more complex user API?

Since you're using pointer semantics in those options, be careful with races - users might not be aware that you're passing the pointer around (instead of copy) and this could lead to surprises for users. I suggest using value semantic to avoid races and these surprises.
@cx-joses what's the status of this one? |
