There is no reason to re-assign a variable to itself. Either this statement is redundant and should be removed, or the re-assignment is a mistake and some other value or variable was intended for the assignment instead.

Noncompliant Code Example

func (user *User) rename(name string) {
  name = name  // Noncompliant
}

Compliant Solution

func (user *User) rename(name string) {
  user.name = name
}
