Implementations

source

impl<'a> Repr<'a>

source

pub fn parse<T>(
 packet: &Packet<&'a T>,
 src_addr: &IpAddress,
 dst_addr: &IpAddress,
 checksum_caps: &ChecksumCapabilities
) -> Result<Repr<'a>> where
 T: AsRef<[u8]> + ?Sized,

Parse a Transmission Control Protocol packet and return a high-level representation.

source

pub fn header_len(&self) -> usize

Return the length of a header that will be emitted from this high-level representation.

This should be used for buffer space calculations. The TCP header length is a multiple of 4.

source

pub fn buffer_len(&self) -> usize

Return the length of a packet that will be emitted from this high-level representation.

source

pub fn emit<T>(
 &self,
 packet: &mut Packet<&mut T>,
 src_addr: &IpAddress,
 dst_addr: &IpAddress,
 checksum_caps: &ChecksumCapabilities
) where
 T: AsRef<[u8]> + AsMut<[u8]> + ?Sized,

Emit a high-level representation into a Transmission Control Protocol packet.

source

pub fn segment_len(&self) -> usize

Return the length of the segment, in terms of sequence space.

source

pub fn is_empty(&self) -> bool

Return whether the segment has no flags set (except PSH) and no data.
