在 Go 语言中,时间包提供了确定和查看时间的功能。 Go 语言中的Nanoseconds()函数用于以整数纳秒计数的形式查找持续时间。而且,这个函数是在time包下定义的。在这里,您需要导入“time”包才能使用这些功能。
句法:
func (d Duration) Nanoseconds() int64
这里,d 是持续时间。
返回值:它将持续时间值返回为 int64。
示例 1:
// Golang program to illustrate the usage of
// Nanoseconds() function
// Including main package
package main
// Importing fmt and time
import (
"fmt"
"time"
)
// Calling main
func main() {
// Defining duration
// of Nanoseconds method
nano, _ := time.ParseDuration("8s")
// Prints duration as int64
fmt.Printf("Only %d nanoseconds of"+
" task is remaining.", nano.Nanoseconds())
}
输出:
Only 8000000000 nanoseconds of task is remaining.
示例 2:
// Golang program to illustrate the usage of
// Nanoseconds() function
// Including main package
package main
// Importing fmt and time
import (
"fmt"
"time"
)
// Calling main
func main() {
// Defining duration of Nanoseconds method
nano, _ := time.ParseDuration("56m7855s576567576ms")
// Prints duration as int64
fmt.Printf("Only %d nanoseconds of task"+
" is remaining.", nano.Nanoseconds())
}
输出:
Only 587782576000000 nanoseconds of task is remaining.
