Struct etherparse::Ethernet2Slice

pub struct Ethernet2Slice<'a> { /* private fields */ }

Slice containing an Ethernet 2 headers & payload.

Implementations

impl<'a> Ethernet2Slice<'a>

pub fn from_slice_without_fcs( slice: &'a [u8] ) -> Result<Ethernet2Slice<'a>, LenError>

Try creating a Ethernet2Slice from a slice containing the Ethernet 2 header & payload WITHOUT an FCS (frame check sequence) at the end.

pub fn from_slice_with_crc32_fcs( slice: &'a [u8] ) -> Result<Ethernet2Slice<'a>, LenError>

Try creating a Ethernet2Slice from a slice containing the Ethernet 2 header & payload with a CRC 32 bit FCS (frame check sequence) at the end.

In case you are not sure if your ethernet2 frame has a FCS or not use Ethernet2Slice::from_slice_without_fcs instead and rely on the lower layers (e.g. IP) to determine the correct payload length.

pub fn slice(&self) -> &'a [u8]

Returns the slice containing the ethernet 2 header payload and FCS if present.

pub fn destination(&self) -> [u8; 6]

Read the destination MAC address

pub fn source(&self) -> [u8; 6]

Read the source MAC address

pub fn ether_type(&self) -> EtherType

Read the ether_type field of the header indicating the protocol after the header.

pub fn fcs(&self) -> Option<[u8; 4]>

Returns the frame check sequence if present.

pub fn to_header(&self) -> Ethernet2Header

Decode all the fields and copy the results to a Ethernet2Header struct

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

Slice containing the Ethernet 2 header.

pub fn payload(&self) -> EtherPayloadSlice<'a>

Returns the slice containing the Ethernet II payload & ether type identifying it’s content type.

pub fn payload_slice(&self) -> &'a [u8]

Returns the slice containing the Ethernet II payload.

pub const fn header_len(&self) -> usize

Length of the Ethernet 2 header in bytes (equal to crate::Ethernet2Header::LEN).

Trait Implementations

impl<'a> Clone for Ethernet2Slice<'a>

fn clone(&self) -> Ethernet2Slice<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Ethernet2Slice<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Ethernet2Slice<'a>

fn eq(&self, other: &Ethernet2Slice<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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