Structs

A struct is a collection of fields grouped together under one type. Think of it as a lightweight object — no methods required, just data.

Try it: Run the example and see how Vertex{1, 2} prints as {1 2}.

main.go ▶ Run in Playground 
package main

import "fmt"

type Vertex struct {
	X int
	Y int
}

func main() {
	fmt.Println(Vertex{1, 2})
}
