Struct Packet 

pub struct Packet {
    pub header: Header<Ipv4Address>,
    pub pdu: Vec<Segment>,
}

Represents a Network Layer Packet. It contains one or more Segments.

Fields

header: Header<Ipv4Address>

pdu: Vec<Segment>

Implementations

impl Packet

pub fn new(header: Header<Ipv4Address>, pdu: Vec<Segment>) -> Self

Constructs a new instance of the layer.

Trait Implementations

impl Clone for Packet

fn clone(&self) -> Packet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Packet

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

Formats the value using the given formatter.

impl Default for Packet

fn default() -> Self

Returns the “default value” for a type.

impl Display for Packet

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

Formats the value using the given formatter.

impl<'a> IntoIterator for &'a Packet

type Item = &'a <Vec<Segment> as IntoIterator>::Item

The type of the elements being iterated over.

type IntoIter = Iter<'a, <Vec<Segment> as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for Packet

type Item = <Vec<Segment> as IntoIterator>::Item

The type of the elements being iterated over.

type IntoIter = <Vec<Segment> as IntoIterator>::IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Packet

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