Struct fine_grained::Stopwatch

pub struct Stopwatch { /* fields omitted */ }

A stopwatch with lap functionality and nanosecond resolution.

Methods

impl Stopwatch

fn new() -> Stopwatch

Initialize a new stopwatch without starting it.

fn start_new() -> Stopwatch

Initialize a new stopwatch and start it.

fn start(&mut self)

Start the stopwatch.

fn lap(&mut self) -> u64

Start a new lap. Save the last lap's time and return it.

If the stopwatch has not been started, the lap will not be saved and 0 will be returned.

fn stop(&mut self)

Stop the stopwatch, without updating the total time.

This will not reset the stopwatch, i.e. the total time and the laps will be preserved.

fn reset(&mut self)

Re-initialize the stopwatch without restarting it.

fn restart(&mut self)

Re-initialize the stopwatch and start it.

fn total_time(&self) -> u64

Get the total time the stopwatch has been running.

If the stopwatch is still running, the total time is the time from starting the stopwatch until now. Otherwise, it is the sum of all laps.

fn laps(&self) -> &Vec<u64>

Get the list of all measured lap times in the order the laps were timed.

fn number_of_laps(&self) -> usize

Get the number of measured laps.

fn is_running(&self) -> bool

Determine if the stopwatch is currently running.
