Go Recover

Recover is used to regain control of a program from panic or error-condition. It stops the terminating sequence and resumes the normal execution. It is called from the deferred function. It retrieves the error value passed through the call of panic. Normally, it returns nil which has no other effect.

Go recover() Example

package main
import (
   "fmt"
)
func main() {
   fmt.Println(SaveDivide(10, 0))
   fmt.Println(SaveDivide(10, 10))
}
func SaveDivide(num1, num2 int) int {
   defer func() {
      fmt.Println(recover())
   }()
   quotient := num1 / num2
   return quotient
}

Output:

runtime error: integer divide by zero
0
<nil>
1
