如何在实体中按多个键对Struct数组进行排序？

package main

import (
    "fmt"
    "sort"
)

type Person struct {
    Name  string
    Age   int
    Score float64
}

type ByName []Person

func (a ByName) Len() int           { return len(a) }
func (a ByName) Swap(i, j int)      { a[i], a[j] = a[j], a[i] }
func (a ByName) Less(i, j int) bool { return a[i].Name < a[j].Name }

type ByAge []Person

func (a ByAge) Len() int           { return len(a) }
func (a ByAge) Swap(i, j int)      { a[i], a[j] = a[j], a[i] }
func (a ByAge) Less(i, j int) bool { return a[i].Age < a[j].Age }

type ByScore []Person

func (a ByScore) Len() int           { return len(a) }
func (a ByScore) Swap(i, j int)      { a[i], a[j] = a[j], a[i] }
func (a ByScore) Less(i, j int) bool { return a[i].Score < a[j].Score }

func main() {
    people := []Person{
        {Name: "Alice", Age: 25, Score: 85.5},
        {Name: "Bob", Age: 30, Score: 90.0},
        {Name: "Charlie", Age: 20, Score: 80.0},
    }

    // 按照姓名排序
    sort.Sort(ByName(people))
    fmt.Println("按照姓名排序：", people)

    // 按照年龄排序
    sort.Sort(ByAge(people))
    fmt.Println("按照年龄排序：", people)

    // 按照分数排序
    sort.Sort(ByScore(people))
    fmt.Println("按照分数排序：", people)
}
