			patrickelectricUnsubmitted Done You should emit only the error enum and create a function that translate this enum to human string. Emitting strings will make harder to any printer host to identify if the error is really serious or not. patrickelectric: You should emit only the error enum and create a function that translate this enum to human…
			rizzitelloAuthorUnsubmitted Not Done The host will only need to worry about the atcore state . If the error is serious atcore will change its state and the client will react. Most of the errors will just be logged. rizzitello: The host will only need to worry about the atcore state . If the error is serious atcore will…
