Reduce the number of templates in Benchmarking 2023-09-08T08:04:31+00:00 Martin Hořeňovský 2023-08-31T19:52:08+00:00 47a2c969380259e899f471edde84f06a6d687dc9 The basic idea was to reduce the number of things dependent on the `Clock` type. To that end, I replaced `Duration<Clock>` with `IDuration` typedef for `std::nanoseconds`, and `FloatDuration<Clock>` with `FDuration` typedef for `Duration<double, std::nano>`. We can generally assume that any clock's duration can be expressed in nanoseconds, as long as we insert `duration_cast`s into the right places. Note that we cannot remove all dependence on `Clock` as a template arguments, because functions that actually measure the elapsed time have to use the Clock. We also changed some template function arguments to pass plain function pointers, so that the actual implementation can be placed into a cpp file.

Cleanup internal includes by splitting out some event structs 2023-03-31T17:31:51+00:00 Martin Hořeňovský 2023-03-31T08:44:29+00:00 9f08097f55eb29a61efcdb4af41952a67e155215 * Split out BenchmarkInfo and BenchmarkStats to their own header * Outline BenchmarkStats<> declaration to separate header * Split out TestRunInfo into its own header These changes let us remove the large `interfaces_reporter.hpp` include from `benchmark.hpp`, and replace it with `interfaces_capture.hpp` in `run_context.hpp`. I also cleaned out `interfaces_repoter.hpp` from reporter headers that depend on `reporter_common_base.hpp`. This will not change anything in the actual inclusion set, but makes it logically more consistent. 
* Split out BenchmarkInfo and BenchmarkStats to their own header
* Outline BenchmarkStats<> declaration to separate header
* Split out TestRunInfo into its own header

These changes let us remove the large `interfaces_reporter.hpp`
include from `benchmark.hpp`, and replace it with
`interfaces_capture.hpp` in `run_context.hpp`.

I also cleaned out `interfaces_repoter.hpp` from reporter headers
that depend on `reporter_common_base.hpp`. This will not change
anything in the actual inclusion set, but makes it logically
more consistent.
