Implementations

impl IpHeader

pub fn read_from_slice(slice: &[u8]) -> Result<(IpHeader, u8, &[u8]), ReadError>

👎Deprecated since 0.10.1: Renamed to IpHeader::from_slice

Renamed to IpHeader::from_slice

pub fn from_slice(slice: &[u8]) -> Result<(IpHeader, u8, &[u8]), ReadError>

Read an IpvHeader from a slice and return the header & unused parts of the slice.

pub fn read<T: Read + Seek + Sized>(
    reader: &mut T
) -> Result<(IpHeader, u8), ReadError>

Reads an IP (v4 or v6) header from the current position.

pub fn write<T: Write + Sized>(&self, writer: &mut T) -> Result<(), WriteError>

Writes an IP (v4 or v6) header to the current position

pub fn header_len(&self) -> usize

Returns the size when the ip header & extensions are serialized

pub fn next_header(&self) -> Result<u8, ValueError>

Returns the last next header number following the ip header and header extensions.

pub fn set_next_headers(&mut self, last_next_header: u8) -> EtherType

Sets all the next_header fields in the ipv4 & ipv6 header as well as in all extension headers and returns the ether type number.

The given number will be set as the last “next_header” or protocol number.

pub fn set_payload_len(&mut self, len: usize) -> Result<(), ValueError>

Tries to set the length field in the ip header given the length of data after the ip header and extension header(s).

If the payload length is too large to be stored in the length fields of the ip header an error is returned.

Note that this function will automatically add the length of the extension headers is they are present.

Trait Implementations

impl Clone for IpHeader

fn clone(&self) -> IpHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IpHeader

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

Formats the value using the given formatter.

impl PartialEq<IpHeader> for IpHeader

fn eq(&self, other: &IpHeader) -> 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.
