Struct RetiredSegment 

pub struct RetiredSegment {
    pub sent_at: Option<Instant>,
    pub size: u64,
    pub was_retransmit: bool,
}

One reliable segment retired by Stream::on_sack — a segment whose sequence a received SACK covered and which has now been removed from the send buffer.

Fields

sent_at: Option<Instant>

When the segment was last (re)transmitted, if it had been sent at all. None means the segment was acknowledged before poll_send ever stamped it (e.g. a duplicate cumulative SACK) — no RTT sample is taken.

size: u64

On-wire payload size of the segment.

was_retransmit: bool

True if the segment had been retransmitted at least once (retries > 0). Per Karn’s algorithm, the caller must NOT sample RTT from such a segment.
