Enum AckCif 

#[non_exhaustive]
pub enum AckCif {
    Full {
        last_ack_seq: u32,
        rtt_us: u32,
        rtt_var_us: u32,
        avail_buf_size: u32,

    },
    Light {

    },
}

The ACK Control Information Field — its shape (Full/Small/Light) is selected by which fields are present on the wire (§3.2.4). Data-carrying ADT: see AckPacket for the label convention rationale.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Full

Full ACK — all seven CIF fields.

Fields

last_ack_seq: u32

Last Acknowledged Packet Sequence Number.

rtt_us: u32

RTT estimate, in microseconds.

rtt_var_us: u32

RTT variance, in microseconds.

avail_buf_size: u32

Available receiver buffer size, in packets.

pkt_recv_rate: u32

Packets receiving rate, in packets per second.

est_link_capacity: u32

Estimated link capacity, in packets per second.

recv_rate_bps: u32

Estimated receiving rate, in bytes per second.

Small

Small ACK — fields up to and including Available Buffer Size.

Fields

last_ack_seq: u32

Last Acknowledged Packet Sequence Number.

rtt_us: u32

RTT estimate, in microseconds.

rtt_var_us: u32

RTT variance, in microseconds.

avail_buf_size: u32

Available receiver buffer size, in packets.

Light

Light ACK — only Last Acknowledged Packet Sequence Number.

Fields

last_ack_seq: u32

Last Acknowledged Packet Sequence Number.
