Struct packet_formats::icmp::Icmpv4TimestampRequest

pub struct Icmpv4TimestampRequest(/* private fields */);

An ICMPv4 Timestamp Request message.

Implementations

impl Icmpv4TimestampRequest

pub fn new(origin_timestamp: u32, id: u16, seq: u16) -> Icmpv4TimestampRequest

Creates an Icmpv4TimestampRequest.

new constructs a new Icmpv4TimestampRequest with the given parameters, and sets the Receive Timestamp and Transmit Timestamp values to zero.

pub fn reply( &self, recv_timestamp: u32, tx_timestamp: u32 ) -> Icmpv4TimestampReply

Reply to a Timestamp Request message.

reply takes the Icmpv4TimestampRequest from a Timestamp Request message, and produces the appropriate Icmpv4TimestampReply value for a Timestamp Reply message. The original Originate Timestamp, ICMP ID, and ICMP Sequence Number are retained, while the Receive Timestamp and Transmit Timestamp are overwritten with the given values.

The Receive Timestamp (recv_timestamp) indicates the time at which the Timestamp Request was first received, while the Transmit Timestamp (tx_timestamp) indicates the time at which the Timestamp Reply was last processed before being sent.
