Struct Icmpv4Timestamp 

pub struct Icmpv4Timestamp { /* private fields */ }

RFC 792 timestamp message body.

Timestamp request (type 13) and timestamp reply (type 14) append three 32-bit timestamps after the fixed ICMP header: the originate timestamp set by the requester, the receive timestamp set when the responder received the request, and the transmit timestamp set when the responder sent the reply. RFC 792 defines each as milliseconds since midnight UT; a sender that cannot supply a standard value may set the high-order bit, so the raw 32-bit values are exposed verbatim rather than reinterpreted.

This layer always encodes exactly 12 bytes. Malformed timestamp lengths (a short or oversized trailing region) are not forced into this layer on decode; they remain a Raw payload so the bytes are never lost.

Implementations

impl Icmpv4Timestamp

pub fn new() -> Self

Set the receive timestamp.

pub fn transmit(self, transmit: u32) -> Self

Set the transmit timestamp.

pub fn originate_value(&self) -> u32

Originate timestamp value.

pub fn receive_value(&self) -> u32

Receive timestamp value.

pub fn transmit_value(&self) -> u32

Transmit timestamp value.
