Struct Stopwatch 

pub struct Stopwatch { /* private fields */ }

A stopwatch for measuring elapsed time with lap support.

Example

use fastmcp_rust::testing::prelude::*;

let mut stopwatch = Stopwatch::new();

// Do first operation
stopwatch.lap("operation_1");

// Do second operation
stopwatch.lap("operation_2");

println!("Total time: {:?}", stopwatch.elapsed());
for (name, duration) in stopwatch.laps() {
    println!("{}: {:?}", name, duration);
}

Implementations

impl Stopwatch

pub fn new() -> Self

Creates a new stopwatch and starts it immediately.

pub fn stopped() -> Self

Creates a stopped stopwatch that starts when start() is called.

pub fn restart(&mut self)

Restarts the stopwatch, clearing all laps.

pub fn lap(&mut self, name: impl Into<String>)

Records a lap with the given name.

The duration is measured from the last lap (or start if no laps).

pub fn elapsed(&self) -> Duration

Returns the total elapsed time since the stopwatch started.

pub fn since_last_lap(&self) -> Duration

Returns the time since the last lap (or start if no laps).

pub fn laps(&self) -> &[(String, Duration)]

Returns all recorded laps.

pub fn lap_count(&self) -> usize

Returns the number of recorded laps.

pub fn get_lap(&self, name: &str) -> Option<Duration>

Returns the lap with the given name, if it exists.

pub fn total_lap_time(&self) -> Duration

Returns the sum of all lap durations.

pub fn stats(&self) -> TimingStats

Returns timing statistics.

pub fn report(&self) -> String

Formats the stopwatch results as a human-readable report.

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

Formats the value using the given formatter.

impl Default for Stopwatch

fn default() -> Self

Returns the “default value” for a type.
