Struct ArpPacket

pub struct ArpPacket<T: AsRef<[u8]>> { /* private fields */ }

A read/write wrapper around an Address Resolution Protocol packet buffer.

Implementations

impl<T: AsRef<[u8]>> Packet<T>

pub const fn new_unchecked(buffer: T) -> Packet<T>

Imbue a raw octet buffer with ARP packet structure.

pub fn new_checked(buffer: T) -> Result<Packet<T>>

Shorthand for a combination of new_unchecked and check_len.

pub fn check_len(&self) -> Result<()>

Ensure that no accessor method will panic if called. Returns Err(Error) if the buffer is too short.

The result of this check is invalidated by calling set_hardware_len or set_protocol_len.

pub fn into_inner(self) -> T

Consume the packet, returning the underlying buffer.

pub fn hardware_type(&self) -> Hardware

Return the hardware type field.

pub fn protocol_type(&self) -> Protocol

Return the protocol type field.

pub fn hardware_len(&self) -> u8

Return the hardware length field.

pub fn protocol_len(&self) -> u8

Return the protocol length field.

pub fn operation(&self) -> Operation

Return the operation field.

pub fn source_hardware_addr(&self) -> &[u8]

Return the source hardware address field.

pub fn source_protocol_addr(&self) -> &[u8]

Return the source protocol address field.

pub fn target_hardware_addr(&self) -> &[u8]

Return the target hardware address field.

pub fn target_protocol_addr(&self) -> &[u8]

Return the target protocol address field.

impl<T: AsRef<[u8]> + AsMut<[u8]>> Packet<T>

pub fn set_hardware_type(&mut self, value: Hardware)

Set the hardware type field.

pub fn set_protocol_type(&mut self, value: Protocol)

Set the protocol type field.

pub fn set_hardware_len(&mut self, value: u8)

Set the hardware length field.

pub fn set_protocol_len(&mut self, value: u8)

Set the protocol length field.

pub fn set_operation(&mut self, value: Operation)

Set the operation field.

pub fn set_source_hardware_addr(&mut self, value: &[u8])

Set the source hardware address field.

Panics

The function panics if value is not self.hardware_len() long.

pub fn set_source_protocol_addr(&mut self, value: &[u8])

Set the source protocol address field.

Panics

The function panics if value is not self.protocol_len() long.

pub fn set_target_hardware_addr(&mut self, value: &[u8])

Set the target hardware address field.

Panics

The function panics if value is not self.hardware_len() long.

pub fn set_target_protocol_addr(&mut self, value: &[u8])

Set the target protocol address field.

Panics

The function panics if value is not self.protocol_len() long.

Trait Implementations

impl<T: AsRef<[u8]>> AsRef<[u8]> for Packet<T>

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl<T: Clone + AsRef<[u8]>> Clone for Packet<T>

fn clone(&self) -> Packet<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + AsRef<[u8]>> Debug for Packet<T>

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

Formats the value using the given formatter.

impl<T: AsRef<[u8]>> Display for Packet<T>

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

Formats the value using the given formatter.

impl<T: PartialEq + AsRef<[u8]>> PartialEq for Packet<T>

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

impl<T: AsRef<[u8]>> PrettyPrint for Packet<T>

fn pretty_print( buffer: &dyn AsRef<[u8]>, f: &mut Formatter<'_>, indent: &mut PrettyIndent, ) -> Result

Write a concise, formatted representation of a packet contained in the provided buffer, and any nested packets it may contain.
