os.Error - string value (Golang)

Question

How do I get the string value of os.Error? ie. assign to a variable.

Answer 1

For example,

package main

import (
    "errors"
    "fmt"
)

func main() {
    err := errors.New("an error message")
    s := err.Error()
    fmt.Printf("type: %T; value: %q\n", s, s)
}

Output:

type: string; value: "an error message"
