Types

type Asset

type Asset struct {
	AppraisedValue int    `json:"AppraisedValue"`
	Color          string `json:"Color"`
	ID             string `json:"ID"`
	Owner          string `json:"Owner"`
	Size           int    `json:"Size"`
}

Asset describes basic details of what makes up a simple asset Insert struct field in alphabetic order => to achieve determinism across languages golang keeps the order when marshal to json but doesn't order automatically
