Struct RetransmitDescriptor 

pub struct RetransmitDescriptor {
    pub seq: u64,
    pub stream_id: u64,
    pub events: Vec<Bytes>,
    pub flags: PacketFlags,
}

Pre-encryption inputs needed to rebuild a packet for retransmission.

The reliable retransmit path used to stash the fully-encrypted packet bytes, but every encrypted packet carries the cipher’s outer counter stamped at build time. Replaying those exact bytes produces the same wire counter on the wire, which the receiver’s update_rx_counter rejects as a replay — making NACK-driven recovery a no-op the first time it fired. Stashing the rebuild inputs instead lets the retransmit driver call PacketBuilder::build with a fresh counter on each retransmit, so the receiver accepts the recovered packet.

Fields

seq: u64

Per-stream sequence number stamped on the packet header.

stream_id: u64

Stream id for the rebuild call.

events: Vec<Bytes>

Pre-encryption event payloads (the same &[Bytes] originally passed to PacketBuilder::build).

flags: PacketFlags

Packet flags as stamped on the original send.
