Span<T> and streams in .NET framework


Span<T> and streams in .NET framework

wish of those help I managed to solve this by writing an extension method for the Stream class and implementing .NET Core's default behaviour for dealing with Span.
code :
    public static int Read(this Stream thisStream, Span<byte> buffer)
    {
        byte[] sharedBuffer = ArrayPool<byte>.Shared.Rent(buffer.Length);
        try
        {
            int numRead = thisStream.Read(sharedBuffer, 0, buffer.Length);
            if ((uint)numRead > (uint)buffer.Length)
            {
                throw new IOException(SR.IO_StreamTooLong);
            }
            new Span<byte>(sharedBuffer, 0, numRead).CopyTo(buffer);
            return numRead;
        }
        finally { ArrayPool<byte>.Shared.Return(sharedBuffer); }
    }
    public static void Write(this Stream thisStream, ReadOnlySpan<byte> buffer)
    {
        byte[] sharedBuffer = ArrayPool<byte>.Shared.Rent(buffer.Length);
        try
        {
            buffer.CopyTo(sharedBuffer);
            thisStream.Write(sharedBuffer, 0, buffer.Length);
        }
        finally { ArrayPool<byte>.Shared.Return(sharedBuffer); }
    }

like below fixes the issue If you are talking about the new Akka streams integration in Play 2.5.x (still M2), then I think this should do the job as a simple valid flow that represents an echo server (with a touch).
code :
  def socket = WebSocket.accept[String, String] {
    request =>
      Flow[String]
        .map(_ + " Back")
  }

this will help Span results from streams are supported in .NET Core 2.1. If you check the current source code of eg Stream you'll see it has overloads like Read(Span) that read into a Span instead of byte[], or Write(ReadOnlySpan) that can write out a ReadOnlySpan instead of a byte[], overloads that use Memory etc.
To target .NET Core 2.1, you'll have to install at least Visual Studio 2017 15.7 Preview 4 or the latest SDK for .NET Core 2.1

I hope this helps you . Scanning the docs it seems it simply collects this information and supplys an entire org.w3c.Document for Java and a scala.xml for scala : play xml requests
That seems highly unlikely to help in your case as you'll end up with a big in memory model. For 100MB of xml you can expect anything up to 700MB of usage to parse.

should help you out As the Exception states NoMaterializer cannot materialize you may need to add a Materializer:
code :
implicit lazy val mat = ActorMaterializer()
implicit lazy val ec = instanceOf[ExecutionContext]
