How Can I Effectively Set Default Values in Go Structs?

Default Values in Go Structs: Exploring Techniques

Struct initialization is a common operation in Go, enabling developers to initialize fields with default or desired values. This question delves into multiple approaches for assigning default values to Go structs, offering insights beyond the standard question of "How to set default values to golang structs?"

One suggested solution involves employing a constructor function. This method allows us to create a new struct instance by explicitly specifying pertinent values. Consider the following example:

// Something is the structure we work with
type Something struct {
    Text string
    DefaultText string
}

// NewSomething creates a new instance of Something
func NewSomething(text string) Something {
    something := Something{}
    something.Text = text
    something.DefaultText = "default text"
    return something
}

In this example, NewSomething is a constructor function that creates a new Something struct instance. It sets the Text field to the specified value and assigns a default value ("default text") to the DefaultText field. By invoking the NewSomething function with a specific text, we can effortlessly initialize a Something struct with desired default values.
