| <p>This option will prevent Hyper’s client from returning an error encountered |
| when parsing a header, except if the error was caused by the character NUL |
| (ASCII code 0), as Chrome specifically always reject those.</p> |
| <p>The ignorable errors are:</p> |

| </ul> |
| <p>If an ignorable error is encountered, the parser tries to find the next |
