init function for structs

I realize that Go does not have classes but pushes the idea of structs instead.

Do structs have any sort of initialization function that can be called similar to a __construct() function of a class?

Example:

type Console struct {
    X int
    Y int
}

func (c *Console) init() {
    c.X = "5"
}

// Here I want my init function to run
var console Console

// or here if I used
var console Console = new(Console)
Solution

  • Go doesn't have implicit constructors. You would likely write something like this.

    package main

import "fmt"

type Console struct {
    X int
    Y int
}

func NewConsole() *Console {
    return &Console{X: 5}
}

var console Console = *NewConsole()

func main() {
    fmt.Println(console)
}

    Output:

    {5 0}
