SCOPED_TIMER_AVERAGED

#define SCOPED_TIMER_AVERAGED

(

name

)

Value:

static int64_t total_count_; \
static blender::timeit::Nanoseconds total_time_; \
static blender::timeit::Nanoseconds min_time_ = blender::timeit::Nanoseconds::max(); \
blender::timeit::ScopedTimerAveraged scoped_timer( \
    name, total_count_, total_time_, min_time_, std::nullopt)

Print the average and minimum runtime of the timer's scope.

Warning

This uses static variables, so it is not thread-safe.

SCOPED_TIMER_ROLLING_AVERAGED

#define SCOPED_TIMER_ROLLING_AVERAGED	(		name,
			window_size )

Value:

static int64_t total_count_; \
static blender::timeit::Nanoseconds total_time_; \
static blender::timeit::Nanoseconds min_time_ = blender::timeit::Nanoseconds::max(); \
blender::timeit::ScopedTimerAveraged scoped_timer( \
    name, total_count_, total_time_, min_time_, window_size)

Print the rolling average and minimum runtime of the timer's scope.

Warning

This uses static variables, so it is not thread-safe.
