Struct ProgressUpdate 

pub struct ProgressUpdate {
    pub completed_bytes: u64,
    pub download_speed: u64,
    pub upload_speed: u64,
}

Progress update sent from a download command to the engine via channel. This decouples the download task from the RequestGroup RwLock: instead of acquiring group.write().await on every batched progress checkpoint, the download task performs a cheap lock-free send and a single aggregator task applies the update to the RequestGroup.

Fields:

• completed_bytes: total bytes downloaded so far for this command.
• download_speed: current download speed in bytes/sec. 0 means the sender did not refresh the speed sample this tick (the aggregator keeps the previously cached value).
• upload_speed: upload speed in bytes/sec (BT only; 0 for HTTP/FTP).

Fields

completed_bytes: u64

Total bytes downloaded so far for this command.

download_speed: u64

Current download speed in bytes/sec (0 if not yet calculated).

upload_speed: u64

Upload speed in bytes/sec (for BT, 0 for HTTP).
