Exhaustive-enum

Exhaustive-enum is an exhaustive enum checker for Go. It can be used to make sure you don't miss any cases when switching over an enumeration.

Method

Find switch statements. For each:

• Find type of expression being switched over.
• Verify if the type is an enum:
  1. exhaustive-enum annotation.
  2. Type has to be a value type (not struct/interface).
  3. Find all exported values in the package of the type definition.
• Verify that all the enum cases are in the switch, or that there's a default case.
