tick
跟时间相关
-
支持 JSON 序列化的 Duration: tick.Dur
-
解析 天/d/周/w/月/month 等标准库不支持的单位
-
Round 规整，100秒以下最多3位数字
-
tick.Sleep()带 context.Context 的休眠 -
tick.SleepRandom()随机休眠 -
tick.Tick()滴答执行 -
func ParseThinkTime(think string) (t *ThinkTime, err error)思考时间 -
tick.Time支持 JSON 反序列化 -
func SleepRandom(ctx context.Context, max time.Duration) -
func Sleep(ctx context.Context, d time.Duration) -
func Jitter(interval, jitter time.Duration) time.Duration在 interval 上增加最大 jitter 随机抖动时间 -
func ParseTime(tm string) (t time.Time, err error)解析时间字符串- 格式1(绝对时间): RFC3339 "2006-01-02T15:04:05Z07:00"
- 格式2(偏移间隔): -10d 10天前的此时
-
func ParseTimeMilli(tm string) (unixMilli int64, err error) -
func Round(d time.Duration) time.Duration格式化，100秒以下规整到最多3位数字 -
func Parse(s string, allowUnits ...string) (time.Duration, []Fraction, error)扩展解析 天/d/周/w/月/month 等标准库不支持的单位

Variables ¶
var ErrUnknownTimeFormat = errors.New("unknown time format")
ErrUnknownTimeFormat defines the error type for unknown time format.
Functions ¶
func FormatTime ¶
FormatTime format time with Java style layout.
func ParseTime ¶
ParseTime 解析时间字符串 格式1(绝对时间): RFC3339 "2006-01-02T15:04:05Z07:00" 格式2(偏移间隔): -10d 10天前的此时
func ParseTimeMilli ¶
func Round ¶
Round rounds a duration with a precision of 3 digits if it is less than 100s. https://stackoverflow.com/a/68870075
Example ¶
package main
import (
"fmt"
"math"
"time"
"github.com/bingoohuang/ngg/tick"
)
func main() {
for i := 0; i < 15; i++ {
d := time.Duration(3.455555 * math.Pow(10, float64(i)))
fmt.Printf("%2d %12v %6s\n", i, d, tick.Round(d))
// original formatted
}
}

func SleepRandom ¶
SleepRandom will sleep for a random amount of time up to max. If the shutdown channel is closed, it will return before it has finished sleeping.
