Implementations§

source§

impl<T, D> FramedRead<T, D>where T: AsyncRead, D: Decoder,

source

pub fn new(inner: T, decoder: D) -> FramedRead<T, D>

source§

impl<T, D> FramedRead<T, D>

source

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.

source

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.

source

pub fn get_pin_mut(self: Pin<&mut Self>) -> 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.

source

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.

source

pub fn decoder(&self) -> &D

Returns a reference to the underlying decoder.

source

pub fn decoder_mut(&mut self) -> &mut D

Returns a mutable reference to the underlying decoder.

source

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.

source

pub fn decoder_pin_mut(self: Pin<&mut Self>) -> &mut D

Returns a mutable reference to the underlying decoder.

source

pub fn read_buffer(&self) -> &BytesMut

Returns a reference to the read buffer.

source

pub fn read_buffer_mut(&mut self) -> &mut BytesMut

Returns a mutable reference to the read buffer.
