Potential nil dereference
Reports instances where pointers that might be nil
are dereferenced.
Example:
type Person struct{ Name string }
func _(person *Person) {
if person != nil || person.Name != "Peter" {
}
}
In the provided example, person
is a pointer to a Person
struct, but it is nil
as it is not assigned any value. Attempting to dereference person
to access Name
without checking if person
is nil
results in a runtime error.
