synopsis: Faster traceEvent and traceMarker, and binary object logging for
  eventlog
description: ghc-trace-events provides faster traceEvent and traceMarker as well
  as arbitrary binary object logging for the eventlog framework. Unlike the
  <http://hackage.haskell.org/package/base/docs/Debug-Trace.html#g:2 eventlog tracing functions in base>,
  all the tracing functions in this library don't evaluate the input if user
  event logging (the
  <https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/runtime_control.html#rts-flag--l%20⟨flags⟩ -lu>
  flag) is disabled, which can give a significant boost in performance. Take a
  look at the benchmark suite for the details.
  .
  This library provies the following modules:
  .
  ["Debug.Trace.String"] Drop-in replacements for the event tracing functions in
  "Debug.Trace".
  ["Debug.Trace.ByteString"] UTF-8 encoded 'ByteString' variant
  of the event tracing functions in "Debug.Trace". It's faster than the 'String'
  variant.
  ["Debug.Trace.Text"] 'Text' variant of the event tracing functions
  in "Debug.Trace". It's faster than the 'String' variant.
  ["Debug.Trace.Binary"] Arbitary binary object logging available for GHC 8.8 or
  later. Unlike the other tracing functions 'Debug.Trace.Binary.traceBinaryEvent'
  takes an arbitrary 'ByteString' object as opposed to a UTF-8
  encoded string.
