Struct etherparse::Ipv4Slice

pub struct Ipv4Slice<'a> { /* private fields */ }

Slice containing the IPv4 headers & payload.

Implementations

impl<'a> Ipv4Slice<'a>

pub fn from_slice(slice: &[u8]) -> Result<Ipv4Slice<'_>, SliceError>

Separates and validates IPv4 headers (including extension headers) in the given slice and determine the sub-slice containing the payload of the IPv4 packet.

Note that his function returns an crate::err::LenError if the given slice contains less data then the total_len field in the IPv4 header indicates should be present.

If you want to ignore these kind of length errors based on the length fields in the IP headers use crate::LaxIpv4Slice::from_slice instead.

pub fn header(&self) -> Ipv4HeaderSlice<'_>

Returns a slice containing the IPv4 header.

pub fn extensions(&self) -> Ipv4ExtensionsSlice<'_>

Returns a slice containing the IPv4 extension headers.

pub fn payload(&self) -> &IpPayloadSlice<'a>

Returns a slice containing the data after the IPv4 header and IPv4 extensions headers.

pub fn payload_ip_number(&self) -> IpNumber

Returns the ip number the type of payload of the IPv4 packet.

This function returns the ip number stored in the last IPv4 header or extension header.

pub fn is_payload_fragmented(&self) -> bool

Returns true if the payload is flagged as being fragmented.

Trait Implementations

impl<'a> Clone for Ipv4Slice<'a>

fn clone(&self) -> Ipv4Slice<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for Ipv4Slice<'a>

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

Formats the value using the given formatter.

impl<'a> From<Ipv4Slice<'a>> for IpSlice<'a>

fn from(value: Ipv4Slice<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<Ipv4Slice<'a>> for NetSlice<'a>

fn from(value: Ipv4Slice<'a>) -> NetSlice<'a>

Converts to this type from the input type.

impl<'a> PartialEq for Ipv4Slice<'a>

fn eq(&self, other: &Ipv4Slice<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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