Implementations

impl<'a> Ipv4Option<'a>

pub fn copied(&self) -> bool

Returns whether this option should be copied on all fragments.

Trait Implementations

impl<'a> Clone for Ipv4Option<'a>

fn clone(&self) -> Ipv4Option<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Ipv4Option<'a>

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

Formats the value using the given formatter.

impl<'a> OptionBuilder for Ipv4Option<'a>

type Layout = Ipv4OptionsImpl

Information about the option’s layout.

fn serialized_len(&self) -> usize

Returns the serialized length, in bytes, of self.

fn option_kind(&self) -> u8

Returns the wire value for this option kind.

fn serialize_into(&self, buffer: &mut [u8])

Serializes self into data.

impl<'a> PartialEq for Ipv4Option<'a>

fn eq(&self, other: &Ipv4Option<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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