Netty5/Codec/HTTP2 5.0.0.Alpha5 · io.netty5.handler.codec.http2.Http2ChannelDuplexHandler

A ChannelHandler providing additional functionality for HTTP/2. Specifically it allows to:

Create new outbound streams using newStream().
Iterate over all active streams using forEachActiveStream(Http2FrameStreamVisitor).

The Http2FrameCodec is required to be part of the ChannelPipeline before this handler is added, or else an IllegalStateException will be thrown.
