Classes
class	flow::perf::Checkpointing_timer
	The central class in the perf Flow module, this efficiently times the user's operation, with a specified subset of timing methods; and with the optional ability to time intermediate checkpoints within the overall operation. More...
struct	flow::perf::Checkpointing_timer::Checkpoint
	The entirety of the information recorded with each Checkpointing_timer::checkpoint() call; it contains the Duration values (for each Clock_type) with the time elapsed since either the preceding T.checkpoint() or construction. More...
class	flow::perf::Checkpointing_timer::Aggregator
	This companion/inner class of Checkpointing_timer provides aggregation of results from many Checkpointing_timers each measuring some user operation being repeated many times; particularly when the operation consists of multiple steps (checkpoints) of interest. More...

Namespaces
namespace	flow
	Catch-all namespace for the Flow project: A collection of various production-quality modules written in modern C++17, originally by ygoldfel.
namespace	flow::perf
	Flow module containing tools for profiling and optimization.

Functions
std::ostream &	flow::perf::operator<< (std::ostream &os, const Checkpointing_timer::Checkpoint &checkpoint)
	Prints string representation of the given Checkpoint to the given ostream. More...
