Error while parsing resolv.conf file

Variants

InvalidUtf8(usize, Utf8Error)

Error that may be returned when the string to parse contains invalid UTF-8 sequences

InvalidValue(usize)

Error returned a value for a given directive is invalid. This can also happen when the value is missing, if the directive requires a value.

InvalidOptionValue(usize)

Error returned when a value for a given option is invalid. This can also happen when the value is missing, if the option requires a value.

InvalidOption(usize)

Error returned when a invalid option is found.

InvalidDirective(usize)

Error returned when a invalid directive is found.

InvalidIp(usize, AddrParseError)

Error returned when a value cannot be parsed an an IP address.

ExtraData(usize)

Error returned when there is extra data at the end of a line.

Trait Implementations

impl Debug for ParseError

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for ParseError

fn fmt(&self, fmt: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for ParseError

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }
