Struct IP6Header

#[repr(C, packed(1))]
pub struct IP6Header {
    pub version_class_flow: [u8; 4],
    pub payload_len: u16,
    pub next_header: u8,
    pub hop_limit: u8,
    pub src_addr: IPAddr,
    pub dst_addr: IPAddr,
}

This is the struct definition for an IPv6 header. It contains (in order) the same fields as a normal IPv6 header.

Fields

version_class_flow: [u8; 4]

payload_len: u16

next_header: u8

hop_limit: u8

src_addr: IPAddr

dst_addr: IPAddr

Implementations

impl IP6Header

pub fn new() -> IP6Header

This function returns an IP6Header struct initialized to the default values.

pub fn decode(buf: &[u8]) -> SResult<IP6Header>

This function is used to transform a raw buffer into an IP6Header struct. This is useful for deserializing a header upon reception.

Arguments

buf - The serialized version of an IPv6 header

Return Value

SResult<IP6Header> - The resulting decoded IP6Header struct wrapped in an SResult

pub fn encode(&self, buf: &mut [u8]) -> SResult<usize>

This function transforms the self instance of an IP6Header into a byte array

Arguments

buf - A mutable array where the serialized version of the IP6Header struct is written to

Return Value

SResult<usize> - The offset wrapped in an SResult

pub fn get_next_header(&self) -> u8

pub fn set_next_header(&mut self, new_nh: u8)

pub fn get_hop_limit(&self) -> u8

pub fn set_hop_limit(&mut self, new_hl: u8)

pub fn check_transport_checksum(&self, buf: &[u8]) -> Result<(), ErrorCode>

Utility function for verifying whether a transport layer checksum of a received packet is correct. Is called on the assocaite IPv6 Header, and passed the buffer containing the remainder of the packet.
