Struct PieceTracker 

Source 
pub struct PieceTracker { /* private fields */ }
Expand description

Keeps track of missing pieces (as opposed to blocks) and their owners.

Implementations§

Source§

impl PieceTracker

Source

pub fn new(piece_count: usize) -> Self

Source

pub fn missing_pieces_rarest_first(&self) -> impl Iterator<Item = usize> + '_

Get an iterator over the not-yet-downloaded pieces, ordered by the number of peers that own each piece, such that pieces with fewest owners are yielded first.

Source

pub fn get_piece_owners( &self, piece_index: usize, ) -> impl Iterator<Item = &SocketAddr> + Clone

Get addresses of all peers that own a particular piece.

Source

pub fn get_peer_pieces( &self, peer: &SocketAddr, ) -> impl Iterator<Item = usize> + Clone + '_

Get piece indices of all pieces owned by a particular peer.

Source

pub fn has_peer_piece(&self, peer: &SocketAddr, piece_index: usize) -> bool

Check if peer ownes piece_index.

Source

pub fn add_single_record( &mut self, piece_owner: &SocketAddr, piece_index: usize, ) -> bool

Record that piece_owner owns piece_index.

Source

pub fn add_bitfield_record(&mut self, peer: &SocketAddr, bitfield: &Bitfield)

Record that peer owns pieces represented by the bitfield. This won’t invalidate any previous records for the same peer, i.e. it will never remove pieces.

Source

pub fn forget_peer(&mut self, peer: &SocketAddr)

Erase all records pertaining to the specified peer.

Source

pub fn forget_piece(&mut self, piece_index: usize)

Erase all records pertaining to the specified piece.
