Summary
This is a non-behavior-changing refactor to follow-up #9321 by modifying
DisplayParseError
to use owned data and make it useable as a standalone error type (rather than using references and implementingDisplay
). I don't feel very strongly either way. I thought it was awkward that theFormatCommandError
had two branches in the display path, and wanted to represent theParse
vs. other cases as a separate enum, so here we are.
