Struct Ipv6HeaderExt 

pub struct Ipv6HeaderExt<'a> {
    pub header: &'a Ipv6Header,
    pub raw_extensions: &'a [u8],
}

IPv6 Header with extension headers

Fields

header: &'a Ipv6Header

raw_extensions: &'a [u8]

Implementations

impl<'a> Ipv6HeaderExt<'a>

pub fn extensions(&'a self) -> Ipv6ExtensionHeadersIter<'a>

Get IPv6 extension headers iterator

pub fn ext_headers_len(&self) -> usize

Get the total header length including extensions

Methods from Deref<Target = Ipv6Header>

pub fn version(&self) -> u8

Returns the IP version (should always be 6)

pub fn traffic_class(&self) -> u8

Returns the Traffic Class (8 bits) Equivalent to DSCP + ECN in IPv4

pub fn dscp(&self) -> u8

Returns the DSCP portion of Traffic Class (6 bits)

pub fn ecn(&self) -> u8

Returns the ECN portion of Traffic Class (2 bits)

pub fn flow_label(&self) -> u32

Returns the Flow Label (20 bits) Used for QoS and flow identification

pub fn payload_length(&self) -> usize

Returns the payload length in bytes Note: This does NOT include the IPv6 header itself (40 bytes)

pub fn total_length(&self) -> usize

Returns the total packet length (header + payload)

pub fn next_header(&self) -> IpProto

Returns the next header type This indicates the protocol of the next header (TCP, UDP, extension header, etc.)

pub fn hop_limit(&self) -> u8

Returns the hop limit Equivalent to TTL in IPv4

pub fn src_ip(&self) -> Ipv6Addr

Returns the source IPv6 address as Ipv6Addr

pub fn dst_ip(&self) -> Ipv6Addr

Returns the destination IPv6 address as Ipv6Addr

pub fn src_ip_raw(&self) -> [u8; 16]

Returns the source IPv6 address as raw bytes

pub fn dst_ip_raw(&self) -> [u8; 16]

Returns the destination IPv6 address as raw bytes

pub fn has_extension_headers(&self) -> bool

Check if this packet uses extension headers

pub fn is_transport_protocol(&self) -> bool

Check if the next header is a transport protocol (TCP/UDP)

pub fn total_header_len(&self, buf: &[u8], bytes_available: usize) -> usize

Calculate the total header length including extension headers

Returns the total length of IPv6 header + all extension headers, or 0 if the packet is fragmented or if there’s an error parsing.

buf should start at the beginning of the IPv6 header and contain at least bytes_available bytes.

pub fn upper_layer_protocol( &self, buf: &[u8], bytes_available: usize, ) -> Option<(IpProto, bool)>

Get the upper layer protocol after skipping all extension headers Returns the protocol number and whether fragmentation was encountered

pub fn should_parse_extensions(&self) -> bool

Check if there are extension headers to parse
