Struct etherparse::Ipv6Header

pub struct Ipv6Header {
    pub traffic_class: u8,
    pub flow_label: u32,
    pub payload_length: u16,
    pub next_header: u8,
    pub hop_limit: u8,
    pub source: [u8; 16],
    pub destination: [u8; 16],
}

IPv6 header according to rfc8200.

Fields

traffic_class: u8

flow_label: u32

If non 0 serves as a hint to router and switches with multiple outbound paths that these packets should stay on the same path, so that they will not be reordered.

payload_length: u16

The length of the payload and extension headers in bytes (0 in case of jumbo payloads).

next_header: u8

Specifies what the next header or transport layer protocol is (see IpTrafficClass for a definitions of ids).

hop_limit: u8

The number of hops the packet can take before it is discarded.

source: [u8; 16]

IPv6 source address

destination: [u8; 16]

IPv6 destination address

Implementations

impl Ipv6Header

pub fn read_from_slice(slice: &[u8]) -> Result<(Ipv6Header, &[u8]), ReadError>

Read an Ipv6Header from a slice and return the header & unused parts of the slice.

pub fn read<T: Read + Seek + Sized>(
    reader: &mut T
) -> Result<Ipv6Header, ReadError>

Reads an IPv6 header from the current position.

pub fn read_without_version<T: Read + Seek + Sized>(
    reader: &mut T,
    version_rest: u8
) -> Result<Ipv6Header, Error>

Reads an IPv6 header assuming the version & flow_label field have already been read.

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

Takes a slice and skips an ipv6 header extensions and returns the next_header id & the slice past the header. NOTE: There must be a ipv6 header extension id given as a traffic_class.

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

Takes a slice & traffic class (identifying the first header type) and returns next_header id & the slice past after all ipv6 header extensions.

pub fn skip_header_extension<T: Read + Seek + Sized>(
    reader: &mut T,
    traffic_class: u8
) -> Result<u8, Error>

Skips the ipv6 header extension and returns the traffic_class

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

Skips all ipv6 header extensions and returns the last traffic_class

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

Writes a given IPv6 header to the current position.

pub fn set_payload_length(&mut self, size: usize) -> Result<(), ValueError>

Sets the field total_length based on the size of the payload and the options. Returns an error if the payload is too big to fit.
