to fully show the possibilities of the workspace model, you might consider putting these dependencies that are shared between producer and consumer in workspace dependencies.

yeah, I just wanted to show how to share a struct, so I feel that this change might confuse the user? WDYT? I don't have a strong opinion here so let me know if you want me to make that change :)

np: comments are a bit mis-aligned here. you say "create our SQS client" when you're just creating the config, then say "send our message" when you create the SQS client.

actually, do you think it makes sense to model the SQS client as shared state here? that'd be best practice.

you're totally right, I've moved it to a shared state!
