So it only seems to make sense in the case of multiple constant declarations of the same type.įor example, we all know about e-commerce, the order system must involve the flow of order status. When the pre-declared iota appears in a constant declaration, its value in the nth constant description will be n (starting from 0). It will be pre-declared as 0, but its value is not fixed at the compile stage. Iota is a special constant that is predeclared in Go. If you use enums instead of integers (or String codes), you increase compile-time checking and avoid errors from passing in invalid constants, and you document which values are legal to use.īTW, overuse of enums might mean that your methods do too much (it's often better to have several separate methods, rather than one method that takes several flags which modify what it does), but if you have to use flags or type codes, enums are the way to go. Examples would be things like type constants (contract status: "permanent", "temp", "apprentice"), or flags ("execute now", "defer execution"). This article will cover several different ways in which you can use iota, and tips on where to be cautious with its use. However, there are several areas where iota may not be appropriate to use.

Iota is a useful concept for creating incrementing constants in Go. You should always use enums when a variable (especially a method parameter) can only take one out of a small set of possible values. GitHub - iotaledger/iota.go: IOTA Go API Library.
