- def bind(interface: String, port: Int, backlog: Int = defaultBacklog, options: Traversable[SocketOption] = Nil, halfClose: Boolean = false, idleTimeout: Duration = Duration.Inf): Source[IncomingConnection, Future[ServerBinding]]
Creates a Tcp.ServerBinding instance which represents a prospective TCP server binding on the given
endpoint
.Creates a Tcp.ServerBinding instance which represents a prospective TCP server binding on the given
endpoint
.Please note that the startup of the server is asynchronous, i.e. after materializing the enclosing pekko.stream.scaladsl.RunnableGraph the server is not immediately available. Only after the materialized future completes is the server ready to accept client connections.
- interface
The interface to listen on
- port
The port to listen on
- backlog
Controls the size of the connection backlog
- options
TCP options for the connections, see pekko.io.Tcp for details
- halfClose
Controls whether the connection is kept open even after writing has been completed to the accepted TCP connections. If set to true, the connection will implement the TCP half-close mechanism, allowing the client to write to the connection even after the server has finished writing. The TCP socket is only closed after both the client and server finished writing. If set to false, the connection will immediately closed once the server closes its write side, independently whether the client is still attempting to write. This setting is recommended for servers, and therefore it is the default setting.

Creates an Tcp.OutgoingConnection without specifying options.
Creates an Tcp.OutgoingConnection without specifying options. It represents a prospective TCP client connection to the given endpoint.
Note that the ByteString chunk boundaries are not retained across the network, to achieve application level chunks you have to introduce explicit framing in your streams, for example using the Framing operators.
