How can I get the string representation of a struct?

Question

For my application, it does not matter if the string is human readable or not.

Answer 1

Attaching a String() function to a named struct allows us to convert a struct to a string.

package main

import "fmt"

type foo struct {
    bar string
}

func (f foo) String() string {
    return fmt.Sprintf("Foo Says: %s", f.bar)
}

func main() {
    fmt.Println(foo{"Hello World!"})
}

output:
Foo Says: Hello World!
