Implementations

impl Ipv4Option

pub fn option_type(&self) -> Ipv4OptionType

Get the option type.

pub fn len(&self) -> usize

Get the serialized length of this option.

pub fn is_empty(&self) -> bool

Check if the option is empty (for variants with data).

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

Serialize the option to bytes.

Trait Implementations

impl Clone for Ipv4Option

fn clone(&self) -> Ipv4Option

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ipv4Option

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

Formats the value using the given formatter.

impl PartialEq for Ipv4Option

fn eq(&self, other: &Ipv4Option) -> 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.
