Struct Framed
pub struct Framed<T, U> { /* private fields */ }
A unified Stream and Sink interface to an underlying I/O object, using the Encoder and Decoder traits to encode and decode frames.
You can create a Framed instance by using the Decoder::framed adapter, or by using the new function seen below.
Cancellation safety
futures_util::sink::SinkExt::send: if send is used as the event in atokio::select!statement and some other branch completes first, then it is guaranteed that the message was not sent, but the message itself is lost.tokio_stream::StreamExt::next: This method is cancel safe. The returned future only holds onto a reference to the underlying stream, so dropping it will never lose a value.
Implementations
impl<T, U> Framed<T, U>where T: AsyncRead + AsyncWrite,
pub fn new(inner: T, codec: U) -> Framed<T, U>
Provides a Stream and Sink interface for reading and writing to this I/O object, using Decoder and Encoder to read and write the raw data.
Raw I/O objects work with byte sequences, but higher-level code usually wants to batch these into meaningful chunks, called “frames”. This method layers framing on top of an I/O object, by using the codec 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 like gzip or TLS, 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 Framed returned by this method, which will break them into separate objects, allowing them to interact more easily.
Note that, for some byte sources, the stream can be resumed after an EOF by reading from it, even after it has returned None. Repeated attempts to do so, without new data available, continue to return None without creating more (closing) frames.
pub fn with_capacity(inner: T, codec: U, capacity: usize) -> Framed<T, U>
Provides a Stream and Sink interface for reading and writing to this I/O object, using Decoder and Encoder to read and write the raw data, with a specific read buffer initial capacity.
Raw I/O objects work with byte sequences, but higher-level code usually wants to batch these into meaningful chunks, called “frames”.

impl<T, U> Framed<T, U>
pub fn from_parts(parts: FramedParts<T, U>) -> Framed<T, U>
Provides a Stream and Sink interface for reading and writing to this I/O object, using Decoder and Encoder to read and write the raw data.
Raw I/O objects work with byte sequences, but higher-level code usually wants to batch these into meaningful chunks, called “frames”. This method layers framing on top of an I/O object, by using the Codectraits 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 like gzip or TLS, which require both read and write access to the underlying object.
This objects takes a stream and a readbuffer and a writebuffer. These field can be obtained from an existing Framed with the into_parts method.
If you want to work more directly with the streams and sink, consider calling split on the Framed returned by this method, which will break them into separate objects, allowing them to interact more easily.

Adapter that converts this stream into an AsyncBufRead. Read more
fn try_all<Fut, F>(self, f: F) -> TryAll<Self, Fut, F>where Self: Sized, F: FnMut(Self::Ok) -> Fut, Fut: Future<Output = bool>,
Attempt to execute a predicate over an asynchronous stream and evaluate if all items satisfy the predicate. Exits early if an Err is encountered or if an Ok item is found that does not satisfy the predicate. Read more
fn try_any<Fut, F>(self, f: F) -> TryAny<Self, Fut, F>where Self: Sized, F: FnMut(Self::Ok) -> Fut, Fut: Future<Output = bool>,
Attempt to execute a predicate over an asynchronous stream and evaluate if any items satisfy the predicate. Exits early if an Err is encountered or if an Ok item is found that satisfies the predicate. Read more
