How to know if a variable of arbitrary type is Zero in Golang?

Question

Because not all types are comparable, e.g. a slice. So we can\'t do this

var v ArbitraryType
v == reflect.Zero(reflect.TypeOf(v)).Interface()

Answer 1

See this post:

Basically you need to have special cases for the non comparable types.
