§completed_length: u64

Bytes already written to disk

BitTorrent

BitTorrent download with piece bitmap

Fields

§bitfield: Vec<u8>

Piece completion bitmap

§num_pieces: Option<u32>

Total number of pieces

§piece_length: Option<u32>

Size of each piece in bytes

§info_hash: Option<String>

Torrent info hash for peer/metadata matching

§metadata_path: Option<String>

Path to cached .torrent metadata file

Metalink

Metalink download with mirror priority

Fields

§mirrors: Vec<MirrorRestoreInfo>
