sealed trait Network[F[_]] extends AnyRef

Provides the ability to work with TCP, UDP, and TLS.

Source
Network.scala
Example: 

  1. import fs2.Stream
import fs2.io.{Network, udp}

def send[F[_]: Network](packet: udp.Packet): F[Unit] =
  Network[F].udpSocketGroup.open().use { socket =>
    socket.write(packet)
  }

    In this example, the F[_] parameter to send requires the Network constraint instead of requiring the much more powerful Async. An instance of Network is available for any effect F which has an Async[F] instance.

Abstract Value Members

  1. abstract def tcpSocketGroup: Resource[F, SocketGroup[F]]

    Returns a TCP SocketGroup as a resource.

    Returns a TCP SocketGroup as a resource.

    The SocketGroup supports both server and client sockets. When the resource is used, a fixed thread pool is created and used to initialize a java.nio.channels.AsynchronousChannelGroup. All network reads/writes occur on this fixed thread pool. The pool size is set to the number of processors returned by Runtime.getRuntime.availableProcessors. To customize this, use tcpSocketGroupWithConfig.

    When the socket group is finalized, the fixed thread pool is terminated and any future reads/writes on sockets created by the socket group will fail.

  2. abstract def tcpSocketGroupWithConfig(nonBlockingThreadCount: Int = 0, nonBlockingThreadFactory: ThreadFactory = ...): Resource[F, SocketGroup[F]]

    Like tcpSocketGroup but allows configuration of the fixed size thread pool used for NIO.

  3. abstract def tlsContext: Builder[F]

    Returns a builder for TLSContext[F] values.

    Returns a builder for TLSContext[F] values.

    For example, Network[IO].tlsContext.system returns a F[TLSContext[F]].

  4. abstract def udpSocketGroup: Resource[F, SocketGroup[F]]

    Returns a UDP SocketGroup as a resource.

    Returns a UDP SocketGroup as a resource.

    The SocketGroup supports both receiving and sending UDP datagrams. When the resource is acquired, a dedicated thread is started, which performs all non-blocking network calls. When the resource is finalized, the thread is terminated and any sockets opened from the socket group are closed.
