Function opencv::core::get_cpu_tick_count

pub fn get_cpu_tick_count() -> Result<i64, String>

Returns the number of CPU ticks.

On platforms where the feature is available, the function returns the number of CPU ticks since the certain event (normally, the system power-on moment). Using this function one can accurately measure the execution time of very small code fragments, for which cv::getTickCount() granularity is not enough.
