Function opencv::core::get_tick_count

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

The function returns the number of ticks since the certain event (e.g. when the machine was turned on). It can be used to initialize cv::RNG or to measure a function execution time by reading the tick count before and after the function call. The granularity of ticks depends on the hardware and OS used. Use cv::getTickFrequency() to convert ticks to seconds.
