Struct etherparse::UdpSlice

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

Slice containing the UDP headers & payload.

Implementations

impl<'a> UdpSlice<'a>

pub fn from_slice(slice: &'a [u8]) -> Result<UdpSlice<'a>, LenError>

Decode length from UDP header and restrict slice to the length of the header including the payload.

Note that this method fall backs to the length of the slice in the case the length field in the UDP header is set to zero.

pub fn from_slice_lax(slice: &'a [u8]) -> Result<UdpSlice<'a>, LenError>

Try decoding length from UDP header and restrict slice to the length of the header including the payload if possible. If not the slice length is used as a fallback value.

Note that this method fall also backs to the length of the slice in the case the length field in the UDP header is set to zero or smaller then the minimum header length.

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

Return the slice containing the UDP header & payload.

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

Return the slice containing the UDP header.

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

Returns the slice containing the UDP payload.

pub fn payload_len_source(&self) -> LenSource

Value that was used to determine the length of the payload.

pub fn source_port(&self) -> u16

Reads the “udp source port” in the UDP header.

pub fn destination_port(&self) -> u16

Reads the “udp destination port” in the UDP header.

pub fn length(&self) -> u16

Reads the “length” field in the UDP header.

pub fn checksum(&self) -> u16

Reads the “checksum” from the slice.

pub const fn header_len(&self) -> usize

Length of the UDP header (equal to crate::UdpHeader::LEN).

pub const fn header_len_u16(&self) -> u16

Length of the UDP header in an u16 (equal to crate::UdpHeader::LEN_U16).

pub fn to_header(&self) -> UdpHeader

Decode all the fields of the UDP header and copy the results to a UdpHeader struct.

Trait Implementations

impl<'a> Clone for UdpSlice<'a>

fn clone(&self) -> UdpSlice<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for UdpSlice<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for UdpSlice<'a>

fn eq(&self, other: &UdpSlice<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
