Struct Stopwatch 

pub struct Stopwatch {
    pub spans: Vec<TimeSpan>,
}

A stopwatch used to calculate time differences.

Example

use stopwatch2::*;

let mut s = Stopwatch::default();
s.start(); // Starts the stopwatch.
s.start(); // Creates a new time span, which are commonly called "splits".
s.stop(); // Stops the stopwatch.
println!("{}", s); // Prints the total time.
println!("{:?}", s); // Prints the different time spans as debug information.
let total_time = s.elapsed(); // returns the total time as a Duration.
for span in &s.spans {
    println!("{:?} -> {:?}", span.start, span.stop);
}
s.spans.clear(); // Reset the stopwatch.
println!("{}", s); // Prints the total time.
println!("{:?}", s); // Prints the different time spans as debug information.

Fields

spans: Vec<TimeSpan>

All the time spans that this stopwatch has been or is still running. Only the last timespan is allowed to have no stop value, which means it is still active.

Implementations

impl Stopwatch

pub fn start(&mut self) -> Option<TimeSpan>

Starts the stopwatch.

If it is already started, it will create a new split. This means it will stop and start the stopwatch, creating a new TimeSpan in the process.

pub fn stop(&mut self) -> Option<TimeSpan>

Stops the stopwatch without resetting it.

pub fn is_running(&self) -> bool

Returns whether the stopwatch is running.

pub fn elapsed(&self) -> Duration

Returns the total elapsed time accumulated inside of this stopwatch.

Trait Implementations

impl Clone for Stopwatch

fn clone(&self) -> Stopwatch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Stopwatch

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Stopwatch

fn default() -> Stopwatch

Returns the “default value” for a type.

impl Display for Stopwatch

Prints the total time this Stopwatch has run.

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
