Compare a string against a struct field within a slice of structs (sort.Search golang)

type user struct {
	name string
	age  int
}
data := []user{
	{
		name: "timothy",
		age:  23,
	},
	{
		name: "johnson",
		age:  45,
	},
	{
		name: "jason",
		age:  44,
	},
	{
		name: "handson",
		age:  15,
	},
	{
		name: "andrew",
		age:  41,
	},
}
fmt.Println(data)
val := "johnson"
found := false
i := sort.Search(len(data), func(i int) bool {
	println(i)
	return data[i].name == val
})
if i < len(data) && data[i].name == val {
	found = true
}
fmt.Println(val, found)

I tried to search for a string within an array of structs that including some string fields, but couldn't get a match, for example using johnson or andrew. What is the problem? Thank you!

This sorts the data into order, then does a search on it.

I had to declare a type users which is an slice of user,
then implement Len/Cmp/Swap for users type

The sort.Search function uses >=

package main

import (
	"fmt"
	"sort"
)

type user struct {
	name string
	age  int
}

type users []user

func (o users) Len() int           { return len(o) }
func (o users) Less(i, j int) bool { return o[i].name < o[j].name }
func (o users) Swap(i, j int)      { o[i], o[j] = o[j], o[i] }
func main() {
	data := users{
		{
			name: "timothy",
			age:  23,
		},
		{
			name: "johnson",
			age:  45,
		},
		{
			name: "jason",
			age:  44,
		},
		{
			name: "handson",
			age:  15,
		},
		{
			name: "andrew",
			age:  41,
		},
	}
	sort.Sort(data)
	fmt.Println(data)

	val := "johnson"
	found := false
	i := sort.Search(len(data), func(i int) bool {
		println(i)
		return data[i].name >= val
	})
	if i < len(data) && data[i].name == val {
		found = true
	}
	fmt.Println(val, found)
	return
}
