Struct UdpDatagram &nbsp; Copy item path

impl<T: NetworkBytes + Debug> UdpDatagram<'_, T>

pub fn from_bytes_unchecked(bytes: T) -> Self

Interprets bytes as a UDP datagram without any validity checks.

§Panics

This method does not panic, but further method calls on the resulting object may panic if bytes contains invalid input.

pub fn from_bytes( bytes: T, verify_checksum: Option<(Ipv4Addr, Ipv4Addr)>, ) -> Result<Self, UdpError>

Interprets bytes as a UDP datagram if possible or returns the reason for failing to do so.

pub fn source_port(&self) -> u16

Returns the source port of the UDP datagram.

pub fn destination_port(&self) -> u16

Returns the destination port of the UDP datagram.

pub fn len(&self) -> u16

Returns the length of the datagram from its header.

pub fn checksum(&self) -> u16

Returns the checksum value of the packet.

pub fn payload(&self) -> &[u8] ⓘ

Returns the payload of the UDP datagram as an [&u8] slice.

pub fn compute_checksum(&self, src_addr: Ipv4Addr, dst_addr: Ipv4Addr) -> u16

Computes the checksum of a UDP datagram.

impl<T: NetworkBytesMut + Debug> UdpDatagram<'_, T>

pub fn write_incomplete_datagram( buf: T, payload: &[u8], ) -> Result<Incomplete<Self>, UdpError>

Writes an incomplete UDP datagram, which is missing the checksum, src_port and dst_port fields.

§Arguments
