As its name implies, this provides a method to conveniently measure time elapsed between two code points.
Stopwatch implements a simple stopwatch functionality. Features :
- An alternate time source can be substituted.
- The value returned can be interpreted as relative to another timestamp provided by timeunit.
- Several possible ways to create a Stopwatch.
- Start/Stop at any time or Reset.
- Take an individual Lap time.
- Stores the list of each Lap.
- Handy methods for print the times.
Any given Stopwatch instance records elapsed time. In other words, you can start and stop the stopwatch multiple times (just don't start an already started stopwatch and don't stop an already stopped stopwatch) stopwatch is to be used to measure independent events.

$ go get github.com/sadlil/stopwatch// create a new stopwatch from the current time and stopwatch is not started
s := stopwatch.New()
// create a new stopwatch from the current time and stopwatch is started
s := stopwatch.NewStarted()
// create a new stopwatch from a provided time and stopwatch is not started
s := stopwatch.NewFrom(time.Time{})
// create a new stopwatch from a provided time and stopwatch is started
s:= stopwatch.NewStartedFrom(time.Time{})// start any stopped stopwatch.
s.Start() // if the stopwatch is already started it will return
// the stopwatch instance and an error. Will not affect the stopwatch.
// stop a running stopwatch
s.Stop() // if the stopwatch is already stopped it will return
// the stopwatch instance and an error. Will not affect the stopwatch.
// reset any stopwatch. this usually clears all the data stored.
s.Reset()// return elapsed time in provided timeunit
s.Elapsed(timeunit.TimeUnit) // provided timeunit is a indicator to return the
// result in desired unit. Ex : timeunit.MILLISECONDS
// will return the elapsed time in milliseconds.
// return elapsed time in Nanoseconds
s.ElapsedNanos()
// return elapsed time in go time.Time
s.ElapsedTime()
// return elapsed time in go time.Duration
s.ElapsedDuration()
// return elapsed time in string. basically a go duration.String()
s.ElapsedString()a helper to directly print the elapsed time with ease.
// prints the elapsed time in string
s.PrintString()
// print the elapsed time in provided timeunit
s.Print(timeunit.TimeUnit)utilities for work with laps in the stopwatch.
// adds a lap in the stopwatch with a unique key name
s.AddLap(name)
// get the lap time by name, time will converted to desired timeunit
s.GetLap(name, timeunit.TimeUnit)
// get the lap time in string by name
s.GetLapString()
// get the lap time in nanoseconds by name
s.GetLapNanos(name)
// get all laps name with time in go time.Duration
s.GetLaps()
// helper print functions to print the lap directly.
// prints the lap time in desired timeunit
s.PrintLap(name, timeunit.TimeUnit)
// prints the lap time in string
s.PrintLapString(name)
// print all laps time in string
