Struct TcpReader

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

Reads TCP header fields.

Fields

bytes: &'a [u8]

Implementations

impl<'a> TcpReader<'a>

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

Creates a new TcpReader from the given 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 sequence_number(&self) -> u32

Returns the sequence number field.

pub fn ack_number(&self) -> u32

Returns the acknowledgment number field.

pub fn data_offset(&self) -> u8

Returns the data offset field.

pub fn reserved(&self) -> u8

Returns the reserved field.

pub fn flags(&self) -> u8

Returns the flags field.

pub fn window_size(&self) -> u16

Returns the window size field.

pub fn checksum(&self) -> u16

Returns the checksum field.

pub fn urgent_pointer(&self) -> u16

Returns the urgent pointer field.

pub fn header_len(&self) -> usize

Returns the header length in bytes by multiplying the data offset.

pub fn header(&self) -> Result<&'a [u8], &'static str>

Returns a reference to the header.

pub fn payload(&self) -> Result<&'a [u8], &'static str>

Returns a reference to the payload.

Trait Implementations

impl Debug for TcpReader<'_>

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

Formats the value using the given formatter.

impl<'a> ParseReader<'a> for TcpReader<'a>

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

Parses a TCP segment from a byte slice.

Validates the TCP header length and flags fields.

impl<'a> PartialEq for TcpReader<'a>

fn eq(&self, other: &TcpReader<'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.
