Error flags raised while parsing DNS - to be used in the returned Message

Variants

ExtraOptRr

more than one pseudo-RR exists - EDNS specs limit OPT RRs to <=1

UnknownOpcode

invalid opcode

UnknownRcode

invalid response code

UnknownRclass

invalid record class

UnknownRtype

invalid record type

EdnsParseFail

an option code used in a pseudo-RR is invalid

DnsLabelExceedsMaxLen

some label exceeds the maximum length of 63

DnsNameExceedsMaxLen

name len > 255 - name will be truncated to max_domain_len

DnsNameInvalidCompression

a ptr either points to an invalid location or is self-referential

Trait Implementations

impl Binary for ErrorFlags

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

Formats the value using the given formatter.

impl BitAnd<ErrorFlags> for ErrorFlags

type Output = Flags<ErrorFlags, <ErrorFlags as Flag>::Primitive>

The resulting type after applying the & operator.

fn bitand(self, other: Self) -> Self::Output

Performs the & operation.

impl BitOr<ErrorFlags> for ErrorFlags

type Output = Flags<ErrorFlags, <ErrorFlags as Flag>::Primitive>

The resulting type after applying the | operator.

fn bitor(self, other: Self) -> Self::Output

Performs the | operation.

impl BitXor<ErrorFlags> for ErrorFlags

type Output = Flags<ErrorFlags, <ErrorFlags as Flag>::Primitive>

The resulting type after applying the ^ operator.

fn bitxor(self, other: Self) -> Self::Output

Performs the ^ operation.

impl Clone for ErrorFlags

fn clone(&self) -> ErrorFlags

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorFlags

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

Formats the value using the given formatter.

impl Display for ErrorFlags

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

Formats the value using the given formatter.

impl Flag for ErrorFlags

type Primitive = u16

Associated primitive numeric type

const ITEMS: &'static [Self] = _

A list of all flag variants in the enum

fn bits(self) -> Self::Primitive

Numeric representation of the variant

fn none() -> Flags<Self>

Flag value when no variants are set

fn all() -> Flags<Self>

Flag value when all variants are set

impl FromStr for ErrorFlags

type Err = ()

The associated error which can be returned from parsing.

fn from_str(val: &str) -> Result<ErrorFlags, Self::Err>

Parses a string s to return a value of this type.

impl Not for ErrorFlags

type Output = Flags<ErrorFlags, <ErrorFlags as Flag>::Primitive>

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq<ErrorFlags> for ErrorFlags

fn eq(&self, other: &ErrorFlags) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<Flags<ErrorFlags, <ErrorFlags as Flag>::Primitive>> for ErrorFlags

fn eq(&self, other: &Flags<Self>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
