traceEvent :: String -> a -> a Source #
Drop-in replacement for traceEvent
but is more efficient
if user tracing in eventlog is disabled.
Note that this function doesn't evaluate the String
if user tracing
in eventlog is disabled.
The input should be shorter than \(2^{16}\) bytes. Otherwise the RTS generates a broken evnetlog.
traceEventIO :: String -> IO () Source #
Drop-in replacement for traceEventIO
but is more efficient
if user tracing in eventlog is disabled.
Note that this function doesn't evaluate the String
if user tracing
in eventlog is disabled.
The input should be shorter than \(2^{16}\) bytes. Otherwise the RTS generates a broken evnetlog.
traceMarker :: String -> a -> a Source #
Drop-in replacement for traceMarker
but is more efficient
if user tracing in eventlog is disabled.
Note that this function doesn't evaluate the String
if user tracing
in eventlog is disabled.
The input should be shorter than \(2^{16}\) bytes. Otherwise the RTS generates a broken evnetlog.
traceMarkerIO :: String -> IO () Source #
Drop-in replacement for traceMarkerIO
but is more efficient
if user tracing in eventlog is disabled.
Note that this function doesn't evaluate the String
if user tracing
in eventlog is disabled.
The input should be shorter than \(2^{16}\) bytes. Otherwise the RTS generates a broken evnetlog.
