Events emitted by one of the installed transports to protocol(s).

Variants

ConnectionEstablished

Connection established to peer.

Fields

peer: PeerId

Peer ID.

endpoint: Endpoint

Endpoint.

ConnectionClosed

Connection closed to peer.

Fields

peer: PeerId

Peer ID.

DialFailure

Failed to dial peer.

This is reported to that protocol which initiated the connection.

Fields

peer: PeerId

Peer ID.

address: Multiaddr

Dialed address.

SubstreamOpened

Substream opened for peer.

Fields

peer: PeerId

Peer ID.

protocol: ProtocolName

Protocol name.

One protocol handler may handle multiple sub-protocols (such as /ipfs/identify/1.0.0 and /ipfs/identify/push/1.0.0) or it may have aliases which should be handled by the same protocol handler. When the substream is sent from transport to the protocol handler, the protocol name that was used to negotiate the substream is also sent so the protocol can handle the substream appropriately.

fallback: Option<ProtocolName>

Fallback protocol.

direction: Direction

Substream direction.

Informs the protocol whether the substream is inbound (opened by the remote node) or outbound (opened by the local node). This allows the protocol to distinguish between the two types of substreams and execute correct code for the substream.

Outbound substreams also contain the substream ID which allows the protocol to distinguish between different outbound substreams.

substream: Substream

Substream.

SubstreamOpenFailure

Failed to open substream.

Substream open failures are reported only for outbound substreams.

Fields

substream: SubstreamId

Substream ID.

error: SubstreamError

Error that occurred when the substream was being opened.
