R/futureSessionInfo.R
futureSessionInfo.RdGet future-specific session information and validate current backend
futureSessionInfo(test = TRUE, anonymize = TRUE)If TRUE, one or more futures are created to query workers and validate their information.
If TRUE, user names and host names are anonymized.
Nothing.
