Fields

ethernet: Option<EthernetReader<'a>>

ipv4: Option<IPv4Reader<'a>>

tcp: Option<TcpReader<'a>>

udp: Option<UdpReader<'a>>

icmp: Option<IcmpReader<'a>>

Implementations

impl<'a> PacketParser<'a>

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

Parses a raw Ethernet frame.

Is strict about what input it accepts.

pub fn parse_arp(&mut self, bytes: &'a [u8]) -> Result<(), &'static str>

Parses an ARP header.

ARP was originally designed for Ethernet, IPv4 and MAC addresses.

Theoretically, it can also be used with other combinations of protocols.

pub fn parse_ipv4(&mut self, bytes: &'a [u8]) -> Result<(), &'static str>

Parses a IPv4 header.

pub fn parse_icmp(&mut self, bytes: &'a [u8]) -> Result<(), &'static str>

Parses a ICMP header.

pub fn parse_tcp(&mut self, bytes: &'a [u8]) -> Result<(), &'static str>

Parses a TCP header.

pub fn parse_udp(&mut self, bytes: &'a [u8]) -> Result<(), &'static str>

Parses a UDP header.

pub fn verify_checksums(&self) -> Result<(), &'static str>

Verifies the checksums of encapsulated headers.

pub fn header_len(&self) -> usize

Returns the total length of all headers.

Trait Implementations

impl<'a> Debug for PacketParser<'a>

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

Formats the value using the given formatter.
