Struct UdpReader

pub struct UdpReader<'a> {
    pub bytes: &'a [u8],
}

Reads UDP header fields.

Fields

bytes: &'a [u8]

Implementations

impl<'a> UdpReader<'a>

pub fn new(bytes: &'a [u8]) -> Result<Self, &'static str>

Creates a new UdpPacket from the given data slice.

pub fn src_port(&self) -> u16

Returns the source port field.

pub fn dest_port(&self) -> u16

Returns the destination port field.

pub fn checksum(&self) -> u16

Returns the checksum field.

pub fn length(&self) -> u16

Returns the length field.

Includes the entire packet (header and payload).

pub fn header_len(&self) -> usize

Returns the header length in bytes.

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

Returns a reference to the header.

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

Returns a reference to the payload.

Trait Implementations

impl Debug for UdpReader<'_>

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

Formats the value using the given formatter.

impl<'a> ParseReader<'a> for UdpReader<'a>

fn parse(bytes: &'a [u8]) -> Result<Self, &'static str>

Parses a UDP datagram from a byte slice.

Validates the UDP length field against the actual length of the datagram.

impl<'a> PartialEq for UdpReader<'a>

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

Tests for self and other values to be equal, and is used by ==.

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

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