Struct UDPHeader

pub struct UDPHeader { /* private fields */ }

The UDPHeader struct follows the layout for the UDP packet header.

Note that the implementation of this struct provides getters and setters for the various fields of the header, to avoid confusion with endian-ness.

Implementations

impl UDPHeader

pub fn new() -> UDPHeader

pub fn get_offset(&self) -> usize

pub fn set_dst_port(&mut self, port: u16)

pub fn set_src_port(&mut self, port: u16)

pub fn set_len(&mut self, len: u16)

pub fn set_cksum(&mut self, cksum: u16)

pub fn get_src_port(&self) -> u16

pub fn get_dst_port(&self) -> u16

pub fn get_len(&self) -> u16

pub fn get_cksum(&self) -> u16

pub fn get_hdr_size(&self) -> usize

pub fn encode(&self, buf: &mut [u8], offset: usize) -> SResult<usize>

This function serializes the UDPHeader into the provided buffer.

Arguments

buf - A mutable buffer to serialize the UDPHeader into offset - The current offset into the provided buffer

Return Value

This function returns the new offset into the buffer wrapped in an SResult.

pub fn decode(buf: &[u8]) -> SResult<UDPHeader>

This function deserializes the UDPHeader from the provided buffer.

Arguments

buf - The byte array corresponding to a serialized UDPHeader

Return Value

This function returns a UDPHeader struct wrapped in an SResult
