1import (2type compiler struct {3}4func (c compiler) structIsVarlen() bool {5}6func main() {7	c := compiler{}8	fmt.Println(c.structIsVarlen())9}10In Go, there are two types of receiver types, value receiver and pointer receiver. If we want to define a method with a pointer receiver, we have to use the pointer symbol (*) before the receiver type. In the first method, we have used a pointer receiver type. The pointer receiver type is also called a pointer method. The pointer receiver type is a method that accepts a pointer to the struct as the receiver. The pointer receiver type is used when we want to modify the struct field values inside the method. The pointer receiver type is also used when we want to avoid copying the struct values. If we use the value receiver type, the value will be copied every time we call the method. If the struct has a large number of fields, it will cause a performance issue. The pointer receiver type avoids this issue. In the second method, we have used a value receiver type. The value receiver type is also called a value method. The value receiver type is a method that accepts a value of the struct as the receiver. The value receiver type is used when we want to read the struct field values inside the metho
