If the error is created by your code, then just reuse the same one. See https://cs.opensource.google/go/go/+/refs/tags/go1.19.3:src/io/io.go;drc=90b40c0496440fbd57538eb4ba303164ed923d93;l=44
If the error is created by code other than your own, and that code does not reuse the same error, then compare strings.
