iszero
A go package for checking if a value is zero.
I put this package together from code within the Go source, because I needed to be able to identify if a field in a struct was empty/its-zero-value, so that when encoding a struct I could determine if the field was empty and could be ommitted.
Usage
See the example in Go Docs.

func Value ¶
Value determines of the value is a zero value, which is the value the type has if declared without a defined value.
Example ¶
package main
import (
"fmt"
"reflect"
"4d63.com/iszero"
)
func main() {
var s0 string
s0Zero := iszero.Value(reflect.ValueOf(s0))
var s1 string = "hello world"
s1Zero := iszero.Value(reflect.ValueOf(s1))
fmt.Println("s0", s0Zero)
fmt.Println("s1", s1Zero)
}
Output: s0 true s1 false
