pub fn set_identifier(&mut self, identifier: u16)

Sets the identifier.

pub fn seq_no(&self) -> u16

Returns the sequence number.

pub fn set_seq_no(&mut self, seq_no: u16)

Sets the sequence number.

pub fn data(&self) -> &[u8]

Returns the data as a u8 slice.

pub fn set_data(&mut self, data: &[u8]) -> Fallible<()>

Trait Implementations

impl<E: Ipv6Packet> Debug for EchoReply<E>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<E: Ipv6Packet> Icmpv6Message for EchoReply<E>

type Envelope = E

The preceding packet type that encapsulates this message.

fn msg_type() -> Icmpv6Type

Returns the assigned message type.

fn icmp(&self) -> &Icmpv6<Self::Envelope>

Returns a reference to the generic ICMPv6 packet.

fn icmp_mut(&mut self) -> &mut Icmpv6<Self::Envelope>

Returns a mutable reference to the generic ICMPv6 packet.

fn into_icmp(self) -> Icmpv6<Self::Envelope>

Converts the message back to the generic ICMPv6 packet.

unsafe fn clone(&self, internal: Internal) -> Self

Returns a copy of the message.

fn try_parse(
    icmp: Icmpv6<Self::Envelope>,
    _internal: Internal
) -> Fallible<Self>

Parses the ICMPv6 packet's payload as this message type.

Prepends a new ICMPv6 message to the beginning of the envelope's payload.

fn reconcile(&mut self)

Reconciles the derivable header fields against the changes made to the packet. The default implementation computes the [checksum] based on the pseudo-header and the ICMPv6 message.

impl<E: Ipv6Packet> Icmpv6Packet for EchoReply<E>

fn msg_type(&self) -> Icmpv6Type

Returns the message type.

fn code(&self) -> u8

Returns the code.

fn set_code(&mut self, code: u8)

Sets the code.

fn checksum(&self) -> u16

Returns the checksum.
