RxLogFailure, RxLogFailureWithBuffer can be used to record an event in
the log. The RxLogFailure, RxLogFailureWithBuffer captures the line
number alongwith the supplied information and writes it to the log. This
is useful in debugging. RxLogFailureDirect, RxLogBufferDirect do not
capture the line number
RxlogEvent is useful for writing events into the log.
