defaults

Defaults lets you define default values for structs. Also, you can add pre-defined validation rules to validate struct fields.

type Instance struct {
	URL      string `default:"https://isacikgoz.me" validate:"url"`
	Login    string `validate:"email"`
	Password string `validate:"notempty"`
}

Examples

To set default values you can simply use as following

var i Instance
err := defaults.Set(&i)
if err != nil {
	panic(err)
}

Or you can validate if the struct fields are valid

i := Instance{
	URL:      "https://isacikgoz.me",
	Login:    "[email protected]",
	Password: "my-super-secret-password",
}

err := defaults.Validate(&i)
if err != nil {
	panic(err)
}
