const DateFormat = "2006-01-02T15:04:05.000-0700"

DateFormat is the date format that ARI returns in the JSON bodies

View Source 
const EndpointIDSeparator = "|" //TODO: confirm separator isn't terrible

EndpointIDSeparator seperates the ID components of the endpoint ID

Variables

var Logger = log15.New()

Logger defaults to a discard handler (null output). If you wish to enable logging, you can set your own handler like so: 

ari.Logger.SetHandler(log15.StderrHandler)

Functions
