Struct BufferedReceiver 

pub struct BufferedReceiver<'d, D>
where
    D: Driver<'d>,
{ /* private fields */ }

CDC ACM class buffered receiver.

It is a requirement of the embedded_io_async::Read trait that arbitrarily small lengths of data can be read from the stream. The Receiver can only read full packets at a time. The BufferedReceiver instead buffers a single packet if the caller does not read all of the data, so that the remaining data can be returned in subsequent calls.

If you have no requirement to use the embedded_io_async::Read trait or to read a data length less than the packet length, then it is more efficient to use the Receiver directly.

You can obtain a BufferedReceiver with Receiver::into_buffered.

Implementations

impl<'d, D> BufferedReceiver<'d, D>

where D: Driver<'d>,

pub fn line_coding(&self) -> LineCoding

Gets the current line coding. The line coding contains information that’s mainly relevant for USB to UART serial port emulators, and can be ignored if not relevant.

pub fn dtr(&self) -> bool

Gets the DTR (data terminal ready) state

pub fn rts(&self) -> bool

Gets the RTS (request to send) state

pub async fn wait_connection(&mut self)

Waits for the USB host to enable this interface

Trait Implementations

impl<'d, D> ErrorType for BufferedReceiver<'d, D>

where D: Driver<'d>,

type Error = EndpointError

Error type of all the IO operations on this type.

impl<'d, D> Read for BufferedReceiver<'d, D>

where D: Driver<'d>,

async fn read( &mut self, buf: &mut [u8], ) -> Result<usize, <BufferedReceiver<'d, D> as ErrorType>::Error>

Read some bytes from this source into the specified buffer, returning how many bytes were read.

async fn read_exact( &mut self, buf: &mut [u8], ) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.
