Measures execution time of a function. Variants return the elapsed duration alongside 0 to 10 returned values from the function.
|
|
|
|
```go
|
|
// Base variant (no return values): Duration
|
|
elapsedOnly := lo.Duration(func() {
|
|
time.Sleep(3 * time.Millisecond)
|
|
})
|
|
_ = elapsedOnly
|
|
|
|
// Zero-return variant: Duration0
|
|
elapsed := lo.Duration0(func() {
|
|
time.Sleep(10 * time.Millisecond)
|
|
})
|
|
_ = elapsed
|
|
|
|
// One-return variant: Duration1
|
|
v, dur := lo.Duration1(func() int {
|
|
time.Sleep(5 * time.Millisecond)
|
|
return 123
|
|
})
|
|
_ = v
|
|
_ = dur
|
|
|
|
// Two-return variant: Duration2
|
|
a, b, elapsed2 := lo.Duration2(func() (int, string) {
|
|
time.Sleep(2 * time.Millisecond)
|
|
return 7, "x"
|
|
})
|
|
_ = a
|
|
_ = b
|
|
_ = elapsed2
|
|
```
