Struct UdpPacket 

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

Zero-copy UDP packet parser.

Implementations

impl<'a> UdpPacket<'a>

pub fn new(buf: &'a [u8]) -> Option<Self>

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

Raw bytes backing this packet.

pub fn source_port(&self) -> u16

pub fn destination_port(&self) -> u16

pub fn length(&self) -> u16

pub fn checksum(&self) -> u16

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

pub fn verify_checksum(&self, src: Ipv4Addr, dst: Ipv4Addr) -> bool
