Struct ClientRecord 

pub struct ClientRecord {
    pub last_seen: f64,
    pub requests: u64,
    pub responses: u64,
    pub dropped: u64,
    pub last_receive: Option<NtpTimestamp>,
    pub last_transmit: Option<NtpTimestamp>,
    pub last_receive_sent: Option<NtpTimestamp>,
    pub interleaved_now: bool,
    /* private fields */
}

Per-client state: enough for rate limiting, interleaved mode and the MRU report, and no more — this is multiplied by every client that has ever spoken to us.

Fields

last_seen: f64

requests: u64

responses: u64

dropped: u64

last_receive: Option<NtpTimestamp>

T2 of the last request we accepted.

last_transmit: Option<NtpTimestamp>

The true transmit timestamp of our last response, once the driver reports it. None until then, which is why interleaved mode cannot answer the very first request.

last_receive_sent: Option<NtpTimestamp>

The receive timestamp we put in our last response. A client asks for interleaved mode by echoing exactly this.

interleaved_now: bool

Whether the last answered request was actually served interleaved.

Distinct from “we could serve it interleaved”: every client we have answered once is capable, but only a client that asks is using it, and an operator reading a client log needs the second fact.
