Struct EthernetFrame

pub struct EthernetFrame<B> { /* private fields */ }

An Ethernet frame.

An EthernetFrame shares its underlying memory with the byte slice it was parsed from or serialized to, meaning that no copying or extra allocation is necessary.

Implementations

impl<B: SplitByteSlice> EthernetFrame<B>

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

The frame body.

pub fn into_body(self) -> B

where B: Copy,

Consumes the frame and returns the body.

pub fn src_mac(&self) -> Mac

The source MAC address.

pub fn dst_mac(&self) -> Mac

The destination MAC address.

pub fn ethertype(&self) -> Option<EtherType>

The EtherType.

ethertype returns the EtherType from the Ethernet header. However, some values of the EtherType header field are used to indicate the length of the frame’s body. In this case, ethertype returns None.

pub fn builder(&self) -> EthernetFrameBuilder

Construct a builder with the same contents as this frame.

Trait Implementations

impl<B: SplitByteSlice> ParsablePacket<B, EthernetFrameLengthCheck> for EthernetFrame<B>

type Error = ParseError

The type of errors returned from parse and parse_mut.

fn parse_metadata(&self) -> ParseMetadata

Gets metadata about this packet required by [GrowBuffer::undo_parse].

fn parse<BV: BufferView<B>>( buffer: BV, length_check: EthernetFrameLengthCheck, ) -> ParseResult<Self>

Parses a packet from a buffer.

fn parse_mut<BV>(buffer: BV, args: ParseArgs) -> Result<Self, Self::Error>

where BV: BufferViewMut<B>, B: SplitByteSliceMut,

Parses a packet from a mutable buffer.
