proc bindAsyncSocket(sock: AsyncFD; ma: MultiAddress): bool {....raises: [LPError],
    raises: [], tags: [RootEffect].}

Bind socket sock to MultiAddress ma.

Note: This procedure only used in go-libp2p-daemon wrapper.

Source Edit

proc connect(ma: MultiAddress; bufferSize = DefaultStreamBufferSize;
             child: StreamTransport = nil; flags = default(set[SocketFlags]);
             localAddress: Opt[MultiAddress] = Opt.none(MultiAddress)): InternalRaisesFuture[
    StreamTransport, (CancelledError, LPError)] {.stackTrace: false, ...raises: [],
    gcsafe, raises: [], raises: [], tags: [RootEffect].}

Open new connection to remote peer with address ma and create new transport object StreamTransport for established connection. bufferSize is size of internal buffer for transport. Source Edit

proc createAsyncSocket(ma: MultiAddress): AsyncFD {....raises: [LPError],
    raises: [], tags: [RootEffect].}

Create new asynchronous socket using MultiAddress' ma socket type and protocol information.

Returns asyncInvalidSocket on error.

Note: This procedure only used in go-libp2p-daemon wrapper.

Source Edit

proc createStreamServer[T](ma: MultiAddress; cbproc: StreamCallback2;
                           flags: set[ServerFlags] = {}; udata: ref T;
                           sock: AsyncFD = asyncInvalidSocket;

                           init: TransportInitCallback = nil): StreamServer {.
    ...raises: [LPError], raises: [].}

Create new TCP stream server which bounds to ma address. Source Edit

proc createStreamServer[T](ma: MultiAddress; flags: set[ServerFlags] = {};
                           udata: ref T; sock: AsyncFD = asyncInvalidSocket;
                           backlog: int = 100;
                           bufferSize: int = DefaultStreamBufferSize;

                           init: TransportInitCallback = nil): StreamServer {.
    ...raises: [LPError], raises: [].}

Create new TCP stream server which bounds to ma address. Source Edit

proc getLocalAddress(sock: AsyncFD): TransportAddress {....raises: [], tags: [].}

Retrieve local socket sock address.

Note: This procedure only used in go-libp2p-daemon wrapper.

Source Edit

proc initTAddress(ma: MultiAddress): MaResult[TransportAddress] {....raises: [],
    tags: [RootEffect].}

Initialize TransportAddress with MultiAddress ma.

MultiAddress must be wire address, e.g. {IP4, IP6, UNIX}/{TCP, UDP}.
