Detailed Description

class to create an observer based on Chrome tracing format

A tf::ChromeObserver inherits tf::ObserverInterface and defines methods to dump the observed thread activities into a format that can be visualized through Chrome Tracing.

tf::Taskflow taskflow;
tf::Executor executor;
 
// insert tasks into taskflow
// ...
  
// create a custom observer
std::shared_ptr<tf::ChromeObserver> observer = executor.make_observer<tf::ChromeObserver>();
 
// run the taskflow
executor.run(taskflow).wait();
 
// dump the thread activities to a chrome-tracing format.
observer->dump(std::cout);
