Avoid naming unused receivers

Why you should care

If the receiver of a method is unused, do not give it a name. It’s more readable because it’s clear that the receiver is not used in method.

How we detect

CAST Highlight counts one occurrence each time a receiver is named and is not used in the method.

// Don't do this:
func (f foo) method() {

// Do this : 
func (foo) method() {
