How to check if two rectangles overlap with each other in Go

Go

package main

import (
	"fmt"
)

type Rectangle struct {
	x1, y1, x2, y2 float64
}

func (r *Rectangle) Overlap(r2 *Rectangle) bool {

if r.x1 > r2.x2 || r.x2 < r2.x1 || r.y1 > r2.y2 || r.y2 < r2.y1 {

return false

} else {

return true

} 
}

func main() {

r := &Rectangle{0, 0, 10, 10} // bottom left corner is (0, 0), top right corner is (10, 10)

fmt.Println("Rectangle 1: ", *r)  // Rectangle 1:  &{0 0 10 10}

fmt.Println("Overlap with rectangle 2? ", r.Overlap(&Rectangle{5, 5, 15, 15})) // Overlap with rectangle 2?  true

fmt.Println("Overlap with rectangle 3? ", r.Overlap(&Rectangle{15, 15, 25, 25})) // Overlap with rectangle 3?  false  
    
    fmt.Println("Overlap with rectangle 4? ", r.Overlap(&Rectangle{-5,-5,-15,-15})) // Overlap with rectangle 4?  false

fmt.Println("Overlap with rectangle 5? ", r.Overlap(&Rectangle{-5,-5,-15,-15})) // Overlap with rectangle 5?  false

fmt.Println("Overlap with rectangle 6? ", r.Overlap(&Rectangle{-5,-5,-15,-15})) // Overlap with rectangle 6?  false

fmt.Println("Overlaps itself ?",r == &Rectangle{0 , 0 , 10 ,10}) // Overlaps itself ? true
