Implementations

impl EdnsOption

pub fn len(&self) -> u16

Returns the length in bytes of the EdnsOption

pub fn is_empty(&self) -> bool

Returns true if the length in bytes of the EdnsOption is 0

Trait Implementations

impl BinEncodable for EdnsOption

fn emit(&self, encoder: &mut BinEncoder<'_>) -> ProtoResult<()>

Write the type to the stream

fn to_bytes(&self) -> ProtoResult<Vec<u8>>

Returns the object in binary form

impl Clone for EdnsOption

fn clone(&self) -> EdnsOption

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EdnsOption

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

Formats the value using the given formatter.

impl<'a> From<&'a EdnsOption> for EdnsCode

fn from(value: &'a EdnsOption) -> EdnsCode

Converts to this type from the input type.

impl<'a> From<&'a EdnsOption> for Vec<u8>

fn from(value: &'a EdnsOption) -> Vec<u8>

Converts to this type from the input type.

impl<'a> From<(EdnsCode, &'a [u8])> for EdnsOption

only the supported extensions are listed right now.

fn from(value: (EdnsCode, &'a [u8])) -> EdnsOption

Converts to this type from the input type.

impl Hash for EdnsOption

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<EdnsOption> for EdnsOption

fn eq(&self, other: &EdnsOption) -> 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 PartialOrd<EdnsOption> for EdnsOption

fn partial_cmp(&self, other: &EdnsOption) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
