Description

Public API for the Mutagen Tracer plugin.

Synopsis

Documentation

Trace the evaluation of a given TraceNode.

This function is intended to be used by the GHC plugin to instrument code.

Tell the tracer plugin to trace this function.

For example:

 {-# ANN myFunction TRACE #-}
 myFunction :: Int -> Int
 myFunction x = x + 1
