Direct comparison of errors
Reports direct comparison of errors, e.g. with ==, and suggests using errors.Is instead.
Since Go 1.13, errors can be wrapped using the fmt.Errorf function with the %w verb. Therefore, direct comparison of errors using the equality check may fail on wrapped errors. The preferred way for checking for a specific error since Go 1.13 is to use the errors.Is function from the standard library.
The quick-fix replaces direct comparison of errors with a call to errors.Is.
Example:
if err == MyError {
fmt.Println("MyErr")
}
After the quick fix is applied:
if errors.Is(err, MyError) {
fmt.Println("MyErr")
}
