Working with Go

Working with Structs

A struct is a data type in Go that is a collection of fields. A struct is the closest Go gets to objects.

Define Struct

// define Dog struct
type Dog struct {
    Name  string
    Color string

Create Instance

Create an instance of a struct type

Spot := Dog{Name: "Spot", Color: "brown"}

An alternative way, create a blank instance, each field is set to its zero value. Access struct fields using dot notation for getting or setting.

var Rover Dog
Rover.Name = "Rover"
Rover.Color = "light tan with dark patches"
