Golang 2.0泛型

官方透露大概在1.17版本会Release。
等待吧。
try catch都无所谓了，没有泛型太难受了。
新的泛型算法是这么写的，大家感兴趣的可以去试试。

package main

import (
    "fmt"
)

// Ordered is a type constraint that matches any ordered type.
// An ordered type is one that supports the <, <=, >, and >= operators.
type Ordered interface {
    type int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64, uintptr, float32, float64, string
}

func Sum[T Ordered](s []T) T {
    var sum T
    for _, v := range s {
        sum += v
    }
    return sum
}

func main() {
    arr := []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
    res := Sum(arr)
    fmt.Println(res)
}
