Expand description
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.
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§
source§impl Ipv6Header
impl Ipv6Header
sourcepub fn read_from_slice(slice: &[u8]) -> Result<(Ipv6Header, &[u8]), ReadError>
👎Deprecated since 0.10.1: Renamed to Ipv6Header::from_slice
pub fn read_from_slice(slice: &[u8]) -> Result<(Ipv6Header, &[u8]), ReadError>
Ipv6Header::from_slice
Renamed to Ipv6Header::from_slice
sourcepub fn from_slice(slice: &[u8]) -> Result<(Ipv6Header, &[u8]), ReadError>
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.
sourcepub fn read<T: Read + Seek + Sized>(
reader: &mut T
) -> Result<Ipv6Header, ReadError>
pub fn read<T: Read + Seek + Sized>(
reader: &mut T
) -> Result<Ipv6Header, ReadError>
Reads an IPv6 header from the current position.
sourcepub fn read_without_version<T: Read + Seek + Sized>(
reader: &mut T,
version_rest: u8
) -> Result<Ipv6Header, Error>
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.
sourcepub fn skip_header_extension_in_slice(
slice: &[u8],
next_header: u8
) -> Result<(u8, &[u8]), ReadError>
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.
sourcepub fn is_skippable_header_extension(ip_protocol_number: u8) -> bool
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.
sourcepub fn skip_all_header_extensions_in_slice(
slice: &[u8],
next_header: u8
) -> Result<(u8, &[u8]), ReadError>
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.
sourcepub fn skip_header_extension<T: Read + Seek + Sized>(
reader: &mut T,
next_header: u8
) -> Result<u8, Error>
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
sourcepub fn skip_all_header_extensions<T: Read + Seek + Sized>(
reader: &mut T,
next_header: u8
) -> Result<u8, ReadError>
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
sourcepub fn write<T: Write + Sized>(&self, writer: &mut T) -> Result<(), WriteError>
pub fn write<T: Write + Sized>(&self, writer: &mut T) -> Result<(), WriteError>
Writes a given IPv6 header to the current position.
sourcepub fn header_len(&self) -> usize
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.
sourcepub fn set_payload_length(&mut self, size: usize) -> Result<(), ValueError>
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.
