[][src]Struct tokio::net::udp::UdpFramed

#[must_use = "sinks do nothing unless polled"]
pub struct UdpFramed<C> { /* fields omitted */ }

A unified Stream and Sink interface to an underlying UdpSocket, 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.

Methods

impl<C> UdpFramed<C>[src]

pub fn new(socket: UdpSocket, codec: C) -> UdpFramed<C>[src]

Create a new UdpFramed backed by the given socket and codec.

See struct level documentation for more details.

pub fn with_decode(
    socket: UdpSocket,
    codec: C,
    repeat_decode: bool
) -> UdpFramed<C>
[src]

Create a new UdpFramed backed by the given socket and codec. That will continue to call decode_eof until the decoder has cleared the entire buffer.

See struct level documentation for more details.

pub fn get_ref(&self) -> &UdpSocket[src]

Returns a reference to the underlying I/O stream wrapped by Framed.

Note

Care should be taken to not tamper with the underlying stream of data coming in as it may corrupt the stream of frames otherwise being worked with.

pub fn get_mut(&mut self) -> &mut UdpSocket[src]

Returns a mutable reference to the underlying I/O stream wrapped by Framed.

Note

Care should be taken to not tamper with the underlying stream of data coming in as it may corrupt the stream of frames otherwise being worked with.

pub fn into_inner(self) -> UdpSocket[src]

Consumes the Framed, returning its underlying I/O stream.
