Function framed 

pub fn framed<C>(stream: Box<dyn ByteStream>, codec: C) -> FramedConn<C>
where
    C: Codec<ByteBuffer> + Clone + 'static,
    C::Error: From<Error> + Into<Error> + Send + Sync,
    C::Message: Send + Sync + 'static,

Convert a ByteStream + codec into a FramedConn. The codec handles both framing and serialization over the byte stream. Call split() for concurrent read/write.
