Implementations

impl TcpPacket

pub fn parse_from_bytes(data: &dyn AsRef<[u8]>) -> Result<Self, TcpParseErr>

Parse a TCP packet and data out of a stream of bytes

This method is meant to be called from the IpPacket::parse_from_bytes method.

Errors

Returns an error if there are not enough bytes for a valid TCP packet.

pub fn pcap_write<W: Write>(&self, file: &mut W) -> Result<()>

Write packet to a pcap file

Writes a tcp packet to a pcap file. This is for use by the write_pcap_file function.

Errors

Will return an error if any of the writes fail.

Performs copy-assignment from source.

impl Debug for TcpPacket

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