Struct IcmpEchoRequest

pub struct IcmpEchoRequest { /* private fields */ }

An ICMP “Echo request” message, suitable for use with crate::socket::IcmpSocket::send_to.

This can be re-used for different requests, if needed.

Sending this ICMP message should result in an “Echo reply” message.

This message supports both IPv4 and IPv6.

See RFC 792 and RFC 4443.

Implementations

impl IcmpEchoRequest

pub fn new() -> Self

Construct a new ICMP “Echo request” message with id and seq set to 0, and empty data.

pub fn from_fields(id: EchoId, seq: EchoSeq, data: &[u8]) -> Self

Construct a new request with the specified id, seq, and data.

data is arbitrary data expected to be returned in the Echo reply.

Some hosts seem to append some zero bytes in the reply.

pub fn id(&self) -> EchoId

The id of the echo request

pub fn seq(&self) -> EchoSeq

The seq num of the echo request

pub fn set_id(&mut self, id: EchoId)

Set a new id number

pub fn set_seq(&mut self, seq: EchoSeq)

Set a new sequence number

pub fn set_data(&mut self, data: &[u8])

Set new data to be echoed
