Matheus, Rewire your brain.
The return value or values may be explicitly listed in the "return" statement. Each expression must be single-valued and assignable to the corresponding element of the function's result type. The Go Programming Language Specification https://go.dev/ref/spec#Return_statements The return &Vertex{X, Y} statement is an implicit assignment to a value of type *Vertex. type Vertex struct { X, Y int } func NewVertex(X, Y int) (v *Vertex) { // return &Vertex{X, Y} v = &Vertex{X, Y} return v } func main() { x, y := 3, 5 var v *Vertex = NewVertex(x, y) fmt.Println(x, y, *v) } https://go.dev/play/p/votlWKXjZH4 peter On Tuesday, March 5, 2024 at 11:33:46 PM UTC-5 Matheus Fassis Corocher wrote: > I was studying about pointers and struct in Golang and one thing that I > don't understand is why using * in return of signature of function instead > of & if the return of function is an address of variable? > > The correct version that works: > > func NewVertex(X, Y int) **Vertex* { > ... > return &Vertex{X, Y} > } > > The version in my mind should be correct: > > func NewVertex(X, Y int) *&Vertex* { > ... > return &Vertex{X, Y} > } > > -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
