Working on the go tour today. I noticed that I could pass struct literals to methods associated with pointer to structs, and vice versa. Why is this allowed?
package main
import (
"fmt"
)
type Vertex struct {
X, Y float64
}
func (v Vertex) Scale (f float64) {
v.X = v.X * f
v.Y = v.Y * f
}
func (v *Vertex) ScaleP(f float64) {
v.X = v.X * f
v.Y = v.Y * f
}
func main() {
v := &Vertex{3, 4}
vLiteral := Vertex{3, 4}
v.Scale(5)
fmt.Println(v)
v.ScaleP(5)
fmt.Println(v)
vLiteral.Scale(5)
fmt.Println(vLiteral)
vLiteral.ScaleP(5)
fmt.Println(vLiteral)
}
Output:
&{3 4}
&{15 20}
{3 4}
{15 20}
