Struct EthernetFrame 

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

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

Implementations

impl<'a> Frame<'a>

pub const fn new_unchecked(buffer: &'a mut [u8]) -> Frame<'a>

Imbue a raw octet buffer with Ethernet frame structure.

pub fn new_checked(buffer: &'a mut [u8]) -> Result<Frame<'a>, Error>

Shorthand for a combination of new_unchecked and check_len.

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

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

pub const fn header_len() -> usize

Return the length of a frame header.

pub const 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.

pub fn dst_addr(&self) -> Address

Return the destination address field.

pub fn src_addr(&self) -> Address

Return the source address field.

pub fn ethertype(&self) -> EtherType

Return the EtherType field, without checking for 802.1Q.

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

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

pub fn set_dst_addr(&mut self, value: Address)

Set the destination address field.

pub fn set_src_addr(&mut self, value: Address)

Set the source address field.

pub fn set_ethertype(&mut self, value: EtherType)

Set the EtherType field.

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

Return a mutable pointer to the payload.

Trait Implementations

impl<'a> AsRef<[u8]> for Frame<'a>

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

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

impl<'a> Debug for Frame<'a>

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

Formats the value using the given formatter.

impl<'a> Display for Frame<'a>

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

Formats the value using the given formatter.

impl<'a> Format for Frame<'a>

where &'a mut [u8]: Format,

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.
