Golang Receiver Function Pointer at Luis Silva blog

Golang Receiver Function Pointer. Comparing the previous two programs, you might notice that functions with a pointer argument must take a pointer: The first is so that the method can modify the value that its receiver points to. In this case, a call to iface.setsomefield works because it can copy the pointer to use as the receiver in the method. In simple terms, value receiver makes a copy of the type and pass it to the function. Pointer receivers are represented by using the type with an asterisk (e.g., func (p *mytype) methodname()). The function stack now holds an equal. There are two reasons to use a pointer receiver. Scalefunc(v, 5) // compile error!. Here's an example of a pointer receiver method in go. In this example, we define a ` circle ` struct and create a pointer. Pointer receivers enable methods to directly access and modify the value referenced by the pointer. I found a workaround using type name func syntax, and then creating a private function that was wrapped in a type bound.
