Is it possible to iterate over all enum values in GoLang?

[hard badge]

Let's say there are three enumerations A, B and C..Is it possible to iterate through all of them?

[acoustic canyon]

go doesn't have enums

there is iota but it's just a cleaver constant trick so no

What should I do to iterate over three types of things that share the same logic?

[acoustic canyon]

I don't understand your question, can you show an example ?

You don't iterate over types (unless you are using reflect but you don't want to do that)

Basically I am using OnThisDay api from Wikipedia and there are three types of events: News, Births And Deaths

Now I want to do a nested loop, first iterate through the three types and then iterate through all of the days of the year and fetch all types of events

[acoustic canyon]

but like thoses are implemented as three different structs ?

No

type IncidentType rune

const (
    Event IncidentType = iota
    Birth
    Death
)

type Incident struct {
    Summary          string
    IncidentType     IncidentType
    IncidentInDetail string
    Year             int
}

[acoustic canyon]

then you just do:

for _, e := range [...]IncidentType{
  Event,
  Birth,
  Death,
}{
  // do stuff
}

it's very great because if you add more elements in the future it's gonna keep compiling even tho you are missing some

an alternative is to defined a global next to the const block but not everyone does this
