Struct subspace_networking :: utils :: piece_provider :: PieceProvider Copy item path

impl<PV> PieceProvider<PV>
where PV: PieceValidator,

pub fn new(node: Node, piece_validator: Option<PV>) -> Self

Creates new piece provider.

pub async fn get_piece_from_cache( &self, piece_index: PieceIndex, ) -> Option<Piece>

Returns piece by its index from farmer’s piece cache (L2)

pub async fn get_piece_from_peer( &self, peer_id: PeerId, piece_index: PieceIndex, ) -> Option<Piece>

Get piece from a particular peer.

pub async fn get_piece_from_archival_storage( &self, piece_index: PieceIndex, max_random_walking_rounds: usize, ) -> Option<Piece>

Get piece from archival storage (L1). The algorithm tries to get a piece from currently connected peers and falls back to random walking.
