Struct UdpFramedRelay
pub struct UdpFramedRelay<C, S> { /* private fields */ }
Expand description
A unified Stream
and Sink
interface to an underlying UdpSocketRelay
, using
the Encoder
and Decoder
traits to encode and decode frames.
Raw UDP sockets work with datagrams, but higher-level code usually wants to
batch these into meaningful chunks, called “frames”. This method layers
framing on top of this socket by using the Encoder
and Decoder
traits to
handle encoding and decoding of messages frames. Note that the incoming and
outgoing frame types may be distinct.
This function returns a single object that is both Stream
and Sink
;
grouping this into a single object is often useful for layering things which
require both read and write access to the underlying object.
If you want to work more directly with the streams and sink, consider
calling split
on the UdpFramed
returned by this method, which will break
them into separate objects, allowing them to interact more easily.
