Struct Ipv4Options 

pub struct Ipv4Options {
    pub options: Vec<Ipv4Option>,
}

Collection of IP options.

Fields

options: Vec<Ipv4Option>

Implementations

impl Ipv4Options

pub fn new() -> Self

Create empty options.

pub fn from_vec(options: Vec<Ipv4Option>) -> Self

Create from a list of options.

pub fn is_empty(&self) -> bool

Check if there are no options.

pub fn len(&self) -> usize

Get the number of options.

pub fn byte_len(&self) -> usize

Get the total serialized length.

pub fn padded_len(&self) -> usize

Get the padded length (aligned to 4 bytes).

pub fn push(&mut self, option: Ipv4Option)

Add an option.

pub fn source_route(&self) -> Option<&Ipv4Option>

Get source route options (LSRR or SSRR).

pub fn final_destination(&self) -> Option<Ipv4Addr>

Get the final destination from source route options.

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

Serialize all options to bytes (with padding).

pub fn copied_options(&self) -> Self

Filter options that should be copied on fragmentation.

Trait Implementations

impl Clone for Ipv4Options

fn clone(&self) -> Ipv4Options

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ipv4Options

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

Formats the value using the given formatter.

impl Default for Ipv4Options

fn default() -> Ipv4Options

Returns the “default value” for a type.

impl<'a> IntoIterator for &'a Ipv4Options

type Item = &'a Ipv4Option

The type of the elements being iterated over.

type IntoIter = Iter<'a, Ipv4Option>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for Ipv4Options

type Item = Ipv4Option

The type of the elements being iterated over.

type IntoIter = IntoIter<Ipv4Option>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Ipv4Options

fn eq(&self, other: &Ipv4Options) -> 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.
