	"gopkg.in/yaml.v3"
)

var data = []byte(`
- name: "apple"
  price: 1
- name: "banana"
- name: "melon"
`)

type Fruit struct {
	Name  string `yaml:"name"`
	Price int    `yaml:"price,omitempty"`
}

func main() {
	var fruits []Fruit
	_ = yaml.Unmarshal(data, &fruits)
	fmt.Printf("%+v", fruits)

package main

import (
	"fmt"

	"gopkg.in/yaml.v3"
)

type Fruit struct {
	Name  string `yaml:"name"`

func main() {
	fruits := []Fruit{
		{Name: "apple", Price: 1},
		{Name: "banana", Price: 0},

	yamlBytes, _ := yaml.Marshal(fruits)
	fmt.Println(string(yamlBytes))
