Struct retina_core::protocols::packet::ipv6::Ipv6

pub struct Ipv6<'a> { /* private fields */ }

An IPv6 packet.

Optional IPv6 extension headers are not parsed by default.

Implementations

impl<'a> Ipv6<'a>

pub fn version(&self) -> u8

Returns the IP protocol version.

pub fn dscp(&self) -> u8

Returns the differentiated services code point (DSCP).

pub fn ecn(&self) -> u8

Returns the explicit congestion notification (ECN).

pub fn traffic_class(&self) -> u8

Returns the traffic class (former name of differentiated services field).

pub fn flow_label(&self) -> u32

Returns the flow label.

pub fn version_to_flow_label(&self) -> u32

Returns the 32-bit field containing the version, traffic class, and flow label.

pub fn payload_length(&self) -> u16

Returns the length of the payload in bytes.

pub fn next_header(&self) -> u8

Returns the encapsulated protocol identifier.

pub fn hop_limit(&self) -> u8

Returns hop limit/time to live of the packet.

pub fn src_addr(&self) -> Ipv6Addr

Returns the sender’s IPv6 address.

pub fn dst_addr(&self) -> Ipv6Addr

Returns the receiver’s IPv6 address.
