Struct Ipv6HeaderSlice

pub struct Ipv6HeaderSlice<'a> { /* private fields */ }

A slice containing an ipv6 header of a network package.

Implementations

impl<'a> Ipv6HeaderSlice<'a>

pub fn from_slice( slice: &'a [u8], ) -> Result<Ipv6HeaderSlice<'a>, HeaderSliceError>

Creates a slice containing an ipv6 header (without header extensions).

pub fn slice(&self) -> &'a [u8]

Returns the slice containing the ipv6 header

pub fn version(&self) -> u8

Read the “version” field from the slice (should be 6).

pub fn traffic_class(&self) -> u8

Read the “traffic class” field from the slice.

pub fn ecn(&self) -> IpEcn

Returns the IpEcn decoded from the traffic_class octet.

pub fn dscp(&self) -> IpDscp

Returns the IpDscp decoded from the traffic_class octet.

pub fn flow_label(&self) -> Ipv6FlowLabel

Read the “flow label” field from the slice.

pub fn payload_length(&self) -> u16

Read the “payload length” field from the slice. The length should contain the length of all extension headers and payload.

pub fn next_header(&self) -> IpNumber

Read the “next header” field from the slice.

The next header value specifies what the next header or transport layer protocol is (see IpNumber or ip_number for a definitions of ids).

pub fn hop_limit(&self) -> u8

Read the “hop limit” field from the slice. The hop limit specifies the number of hops the packet can take before it is discarded.

pub fn source(&self) -> [u8; 16]

Returns a slice containing the IPv6 source address.

pub fn source_addr(&self) -> Ipv6Addr

Return the ipv6 source address as an core::net::Ipv6Addr

pub fn destination(&self) -> [u8; 16]

Returns a slice containing the IPv6 destination address.

pub fn destination_addr(&self) -> Ipv6Addr

Return the ipv6 destination address as an core::net::Ipv6Addr

pub fn to_header(&self) -> Ipv6Header

Decode all the fields and copy the results to a Ipv6Header struct

pub const fn header_len(&self) -> usize

Returns the length of the IPv6 header in bytes (same as crate::Ipv6Header::LEN).

Trait Implementations

impl<'a> Clone for Ipv6HeaderSlice<'a>

fn clone(&self) -> Ipv6HeaderSlice<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Ipv6HeaderSlice<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Ipv6HeaderSlice<'a>

fn eq(&self, other: &Ipv6HeaderSlice<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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