A function can be assigned to a struct and in this case we call it method.
Example:
type Person struct {
Name string
Age int
}
func (p Person) Speak() {
fmt.Println("Hello from " + p.Name)
}
func main() {
flavio := Person{Age: 39, Name: "Flavio"}
flavio.Speak()
}
Methods can be declared to be pointer receiver or value receiver.
The above example shows a value receiver, it receives a copy of the struct instance.
This would be a pointer receiver that receives the pointer to the struct instance:
func (p *Person) Speak() {
fmt.Println("Hello from " + p.Name)
}
