Enums in Odin

A cargo enum, the .Name shorthand, and iteration over the type itself.

package main

import "core:fmt"

Cargo :: enum { General, Reefer, Hazmat }

main :: proc() {
    load := Cargo.Reefer
    // Enum values shorten to .Name where the type is known.
    if load == .Reefer {
        fmt.println("plug it in")
    }

    // The type itself is iterable.
    for kind in Cargo {
        fmt.println(kind, "=", int(kind))
    }
}

How it works

Cargo :: enum { General, Reefer, Hazmat } declares the tags.
Where the type is known, .Reefer needs no prefix.
for kind in Cargo iterates the enum's values; int(kind) shows the ordinals.
