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

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

Methods

impl Ipv6Header

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<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.
