Struct FramedRead
pub struct FramedRead<T, D> { /* private fields */ }
Expand description
A Stream
of messages decoded from an AsyncRead
.
For examples of how to use FramedRead
with a codec, see the
examples on the codec
module.
§Cancellation safety
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, D> FramedRead<T, D>where
T: AsyncRead,
D: Decoder,
impl<T, D> FramedRead<T, D>where
T: AsyncRead,
D: Decoder,
pub fn new(inner: T, decoder: D) -> FramedRead<T, D>
pub fn new(inner: T, decoder: D) -> FramedRead<T, D>
Creates a new FramedRead
with the given decoder
.
pub fn with_capacity(inner: T, decoder: D, capacity: usize) -> FramedRead<T, D>
pub fn with_capacity(inner: T, decoder: D, capacity: usize) -> FramedRead<T, D>
Creates a new FramedRead
with the given decoder
and a buffer of capacity
initial size.
§impl<T, D> FramedRead<T, D>
impl<T, D> FramedRead<T, D>
pub fn get_ref(&self) -> &T
pub fn get_ref(&self) -> &T
Returns a reference to the underlying I/O stream wrapped by
FramedRead
.
Note that 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 T
pub fn get_mut(&mut self) -> &mut T
Returns a mutable reference to the underlying I/O stream wrapped by
FramedRead
.
Note that 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_pin_mut(self: Pin<&mut FramedRead<T, D>>) -> Pin<&mut T>
pub fn get_pin_mut(self: Pin<&mut FramedRead<T, D>>) -> Pin<&mut T>
Returns a pinned mutable reference to the underlying I/O stream wrapped by
FramedRead
.
Note that 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) -> T
pub fn into_inner(self) -> T
Consumes the FramedRead
, returning its underlying I/O stream.
Note that 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 decoder_mut(&mut self) -> &mut D
pub fn decoder_mut(&mut self) -> &mut D
Returns a mutable reference to the underlying decoder.
pub fn map_decoder<C, F>(self, map: F) -> FramedRead<T, C>where
F: FnOnce(D) -> C,
pub fn map_decoder<C, F>(self, map: F) -> FramedRead<T, C>where
F: FnOnce(D) -> C,
Maps the decoder D
to C
, preserving the read buffer
wrapped by Framed
.
pub fn decoder_pin_mut(self: Pin<&mut FramedRead<T, D>>) -> &mut D
pub fn decoder_pin_mut(self: Pin<&mut FramedRead<T, D>>) -> &mut D
Returns a mutable reference to the underlying decoder.
pub fn read_buffer(&self) -> &BytesMut
pub fn read_buffer(&self) -> &BytesMut
Returns a reference to the read buffer.
pub fn read_buffer_mut(&mut self) -> &mut BytesMut
pub fn read_buffer_mut(&mut self) -> &mut BytesMut
Returns a mutable reference to the read buffer.
