Update enum generation to generate a map to validate enums. #2181

AndreasAbdi · 2026-01-09T07:43:36Z

Customers often need to validate whether a value is a legit enum value.
We implement that validation by creating helper functions.

With the helper function, customers no longer have to manually write their own version of the helper.

i.e.

const (
	ClientTypeWithNamesExtensionActive  ClientTypeWithNamesExtension = "ACT"
	ClientTypeWithNamesExtensionExpired ClientTypeWithNamesExtension = "EXP"
)

var ClientTypeWithNamesExtensionValues = map[ClientTypeWithNamesExtension]struct{}{
	ClientTypeWithNamesExtensionActive:  {},
	ClientTypeWithNamesExtensionExpired: {},
}

func (s ClientTypeWithNamesExtension) IsValid() bool {
	_, ok := ClientTypeWithNamesExtensionValues[s]
	return ok
}

and then the customer uses it like:

func legit() {
	k := ClientTypeWithNamesExtension("")
	isValid := k.IsValid()
	fmt.Print(isValid)
}

I'd say we probably shouldn't export the map as then it's mutable outside of the package?
