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

IP protocol number specifying the next header or transport layer protocol.

See IpNumber or ip_number 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>

👎 Deprecated since 0.10.1:

Renamed to Ipv6Header::from_slice

Renamed to Ipv6Header::from_slice

pub fn 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],
    next_header: u8
) -> Result<(u8, &[u8]), ReadError>

Takes a slice and skips an ipv6 header extensions and returns the next_header ip number & the slice past the header.

pub fn is_skippable_header_extension(ip_protocol_number: u8) -> bool

Returns true if the given ip protocol number is a skippable header extension.

A skippable header extension is an extension header for which it is known how to determine the protocol number of the following header as well as how many octets have to be skipped to reach the start of the following header.

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

Takes a slice & ip protocol number (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,
    next_header: u8
) -> Result<u8, Error>

Skips the ipv6 header extension and returns the next ip protocol number

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

Skips all ipv6 header extensions and returns the next ip protocol number

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

Writes a given IPv6 header to the current position.

pub fn header_len(&self) -> usize

Length of the serialized header in bytes.

The function always returns the constant Ipv6Header::SERIALIZED_SIZE and exists to keep the methods consistent with other headers.

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.
