data RunType

There are two typical ways to invoke wrecker. RunCount will execute each a script n times on each thread. So a run count of 100 and a concurrency of 10 will run the script a total of 1000 times. Alternatively, wrecker can run for specified number of seconds with RunTimed.

data DisplayMode

DisplayMode controls how results are displayed in the console. The default is NonInterative which returns the final results at the end of the program. Interactive will show partial results as the program updates.
