While it might be different from it's original intent, in practice,
veilis used mostly for two different use cases:While PII in debug settings is likely to be meaningless and safe to display as plaintext, credentials are best kept always redacted.
This PR introduces a way to mark fields as "secret", meaning credentials, keys, or otherwise security (as opposed to privacy) sensitive fields. It does so by introducing the
#[redact(secret)]marker.Marking a field as "secret" makes it so that it will never be unredacted, regardless of global config. It also makes it so that it's fully redacted, instead of doing it for alphanumeric characters only.
I think we should consider making this the default behavior in future releases, but of course that would be a major breaking change.
