Enum ParseError 

pub enum ParseError {
    HeaderLength(usize),
    HeaderFlag(&'static str, u16),
    InvalidJump,
    ExcesiveJumps(u8),
    LabelPrefix(u8),
    OobRead(usize),
    NonUtf8(Utf8Error),
    InvalidName(NameError),
}

An error was encountered when trying to parse a byte buffer into a DNS packet

Variants

HeaderLength(usize)

The length of the header is too small.

HeaderFlag(&'static str, u16)

Some header flag used a value that has not been implemented.

InvalidJump

There was a jump to a position forward in the packet (it does not follow the specification) or to itself (it is not sound as it would result in a DoS).

ExcesiveJumps(u8)

Some domain name has been compressed with too many jumps. This error may be removed in the future.

LabelPrefix(u8)

The DNS packet contains a label prefix that is not a length prefix or a pointer. Those values dont have a standard definition so are not implemented.

OobRead(usize)

The packet tried to cause an out-of-bound read.

NonUtf8(Utf8Error)

Some text is not valid UTF-8.

InvalidName(NameError)

Error when parsing a domain name

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ParseError

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl From<NameError> for ParseError

fn from(source: NameError) -> Self

Converts to this type from the input type.

impl From<Utf8Error> for ParseError

fn from(source: Utf8Error) -> Self

Converts to this type from the input type.
