Struct smoltcp::wire::EthernetFrame

pub struct EthernetFrame<T: AsRef<[u8]>> { /* fields omitted */ }

A read/write wrapper around an Ethernet II frame buffer.

Methods

impl<T: AsRef<[u8]>> Frame<T>

fn new(buffer: T) -> Result<Frame<T>, Error>

Wrap a buffer with an Ethernet frame. Returns an error if the buffer is too small or too large to contain one.

fn into_inner(self) -> T

Consumes the frame, returning the underlying buffer.

fn buffer_len(payload_len: usize) -> usize

Return the length of a buffer required to hold a packet with the payload of a given length.

fn dst_addr(&self) -> Address

Return the destination address field.

fn src_addr(&self) -> Address

Return the source address field.

fn ethertype(&self) -> EtherType

Return the EtherType field, without checking for 802.1Q.

impl<'a, T: AsRef<[u8]> + ?Sized> Frame<&'a T>

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

Return a pointer to the payload, without checking for 802.1Q.

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

fn set_dst_addr(&mut self, value: Address)

Set the destination address field.

fn set_src_addr(&mut self, value: Address)

Set the source address field.

fn set_ethertype(&mut self, value: EtherType)

Set the EtherType field.

impl<'a, T: AsRef<[u8]> + AsMut<[u8]> + ?Sized> Frame<&'a mut T>

fn payload_mut(&mut self) -> &mut [u8]

Return a mutable pointer to the payload.

fn pretty_print(buffer: &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.
