1、golang基础库，常用的功能

1. redis扩展功能，集群锁、资源控制器等
2. set工具包含：add、has、del，交、差、并计算等
3. uuid一系列功能
4. 携程池
5. 通用util功能集合
6. 简单易用的enum

2、enum

// int类型
e := New[struct {
    First  Elem[int] `code:"1" text:"123"`
    Second Elem[int] `code:"2" text:"123"`
}]()

fmt.Println(Code2Text[int](e))
fmt.Println(e.First.Code, e.First.Text)

// string类型
e := New[struct {
    First  Elem[string] `code:"1" text:"123"`
    Second Elem[string] `code:"2" text:"123"`
}]()

fmt.Println(Code2Text[string](e))
fmt.Println(e.First.Code, e.First.Text)

3、redis

示例代码

// 集群锁
opts := DefaultOptions()
opts.Addr = "127.0.0.1:6379"
opts.DB = 0

r := NewRedis(&opts)
defer r.Close()

lockKey := "test_key"
r.WithLock(lockKey, nil, 10, 3, 500, func () {
    fmt.Println("ok")
})

所有的扩展

4、set集合

s1 := New[string]()
s2 := New[string]()

s1.Add("1", "2", "3")
s2.Add("3", "5", "6")

fmt.Println("Union: ", s1.Union(s2).ToList())
fmt.Println("Intersection: ", s1.Intersection(s2).ToList())
fmt.Println("Difference: ", s1.Difference(s2).ToList())
fmt.Println("SymmetricDifference: ", s1.SymmetricDifference(s2).ToList())

5、uuid

uu, err := NewV4()
if err != nil {
    fmt.Println(err.Error())
}

fmt.Println(uu.String())

6、workpool

wp := NewWorkPool(100, "test", 0, 50)
for i := 0; i < 100; i++ {
    wp.SubmitJob(&JobBag{
        JobFunc: func (i ...interface{}) {
            if i[0].(int)%2 == 0 {
            // panic(fmt.Errorf("1111111111111"))
            }
            fmt.Println("------------", i[0])
        },
        Params: []interface{}{i},
    })
}

for {
    if wp.IsFinished() {
        break
    }
    time.Sleep(time.Millisecond * 10)
}
wp.ShutDownPool()
fmt.Println("done")

7、util
