Struct Bitswap 

pub struct Bitswap {
    pub connected_peers: HashMap<PeerId, Ledger>,
    pub queued_blocks: UnboundedSender<(PeerId, Block)>,
    pub stats: HashMap<PeerId, Arc<Stats>>,
    /* private fields */
}

Network behaviour that handles sending and receiving IPFS blocks.

Fields

connected_peers: HashMap<PeerId, Ledger>

Ledger

queued_blocks: UnboundedSender<(PeerId, Block)>

Blocks queued to be sent

stats: HashMap<PeerId, Arc<Stats>>

Statistics related to peers.

Implementations

impl Bitswap

pub fn local_wantlist(&self) -> Vec<(Cid, Priority)>

Return the wantlist of the local node

pub fn peer_wantlist(&self, peer: &PeerId) -> Option<Vec<(Cid, Priority)>>

Return the wantlist of a peer, if known

pub fn stats(&self) -> Stats

pub fn peers(&self) -> Vec<PeerId>

pub fn connect(&mut self, peer_id: PeerId)

Connect to peer.

Called from Kademlia behaviour.

pub fn send_block(&mut self, peer_id: PeerId, block: Block)

Sends a block to the peer.

Called from a Strategy.

pub fn want_block(&mut self, cid: Cid, priority: Priority)

Queues the wanted block for all peers.

A user request

pub fn cancel_block(&mut self, cid: &Cid)

Removes the block from our want list and updates all peers.

Can be either a user request or be called when the block was received.

Trait Implementations

impl Default for Bitswap

fn default() -> Self

Returns the “default value” for a type.

impl NetworkBehaviour for Bitswap

type ProtocolsHandler = OneShotHandler<BitswapConfig, Message, MessageWrapper>

Handler for all the protocols the network behaviour supports.

type OutEvent = BitswapEvent

Event generated by the NetworkBehaviour and that the swarm will report back.

fn new_handler(&mut self) -> Self::ProtocolsHandler

Creates a new ProtocolsHandler for a connection with a peer.

fn addresses_of_peer(&mut self, _peer_id: &PeerId) -> Vec<Multiaddr>

Addresses that this behaviour is aware of for this specific peer, and that may allow reaching the peer.

fn inject_connected(&mut self, peer_id: &PeerId)

Indicates the behaviour that we connected to the node with the given peer id.

fn inject_disconnected(&mut self, peer_id: &PeerId)

Indicates the behaviour that we disconnected from the node with the given peer id.

fn inject_event( &mut self, source: PeerId, _connection: ConnectionId, message: MessageWrapper, )

Informs the behaviour about an event generated by the handler dedicated to the peer identified by peer_id. for the behaviour.

fn poll( &mut self, ctx: &mut Context<'_>, _: &mut impl PollParameters, ) -> Poll<NetworkBehaviourAction<<<Self::ProtocolsHandler as IntoProtocolsHandler>::Handler as ProtocolsHandler>::InEvent, Self::OutEvent>>

Polls for things that swarm should do.

fn inject_connection_established( &mut self, _: &PeerId, _: &ConnectionId, _: &ConnectedPoint, )

Informs the behaviour about a newly established connection to a peer.

fn inject_connection_closed( &mut self, _: &PeerId, _: &ConnectionId, _: &ConnectedPoint, )

Informs the behaviour about a closed connection to a peer.

fn inject_address_change( &mut self, _: &PeerId, _: &ConnectionId, _old: &ConnectedPoint, _new: &ConnectedPoint, )

Informs the behaviour that the ConnectedPoint of an existing connection has changed.

fn inject_addr_reach_failure( &mut self, _peer_id: Option<&PeerId>, _addr: &Multiaddr, _error: &dyn Error, )

Indicates to the behaviour that we tried to reach an address, but failed.

fn inject_dial_failure(&mut self, _peer_id: &PeerId)

Indicates to the behaviour that we tried to dial all the addresses known for a node, but failed.

fn inject_new_listen_addr(&mut self, _addr: &Multiaddr)

Indicates to the behaviour that we have started listening on a new multiaddr.

fn inject_expired_listen_addr(&mut self, _addr: &Multiaddr)

Indicates to the behaviour that a new multiaddr we were listening on has expired, which means that we are no longer listening in it.

fn inject_new_external_addr(&mut self, _addr: &Multiaddr)

Indicates to the behaviour that we have discovered a new external address for us.

fn inject_listener_error( &mut self, _id: ListenerId, _err: &(dyn Error + 'static), )

A listener experienced an error.

fn inject_listener_closed( &mut self, _id: ListenerId, _reason: Result<(), &Error>, )

A listener closed.
