@phensley Thank you!
Looks good to me but before merge I'd like to see in what context this will be used. Could you please provide more background on this?

[phensley]

The use case we have is for a daemon to be aware of a queue's current size, and whether there are > 0 consumers, and be able to take action.

[kron4eg]

@phensley would it make it for you if cony will expose current *amqp.Connection through some getter?

[phensley]

@kron4eg You could export Connection() (*amqp.Connection, error) and I could move the QueueInspect method into my own code.

[kron4eg]

@phensley yeah, that's what I meant.

[phensley]

@kron4eg Works for me.
