Go language implementation integer self-increment ID generator

This is a creation in Article, where the information may have evolved or changed.

Recently need to implement a self-increment sequence of the growth function, the original practice is to achieve self-growth from the database, but the most recently used sequel Pro can not find the start from the specified value of the self-growth of the settings, only by themselves through the code to find the last item of the database and then add one, So every time you need to add data to look for, it is inconvenient, recently saw this article, benefited, the author provides the program can be directly used, ha ha, hurriedly mark, thank the author.

There will be a lot of surprises when you look at the original.

package mainimport (    "fmt"    "time"    "strconv"    "reflect")type AutoInc struct {    start, step int    queue chan int    running bool}func New(start, step int) (ai *AutoInc) {    ai = &AutoInc{        start: start,        step: step,        running: true,        queue: make(chan int, 4),    }    go ai.process()    return}func (ai *AutoInc) process() {    defer func() {recover()}()    for i := ai.start; ai.running ; i=i+ai.step {        ai.queue <- i    }}func (ai *AutoInc) Id() int {    return <-ai.queue}func (ai *AutoInc) Close() {    ai.running = false    close(ai.queue)}func main() {    var ai *AutoInc    ai = New(100000,1)    for{        a :=ai.Id()        time.Sleep(5*time.Second)        b :=strconv.Itoa(a)        fmt.Println(b,reflect.TypeOf(b))    }}
