Struct VmbusSerialDriver

pub struct VmbusSerialDriver { /* private fields */ }

A connected instance of a vmbus serial port.

Implementations

impl VmbusSerialDriver

pub async fn new( pipe: impl 'static + AsyncRecv + AsyncSend + Send + Unpin + InspectMut, ) -> Result<Self, Error>

Connects to pipe and returns a new serial device instance.

pub async fn drain_rx(&mut self) -> Result<(), Error>

Wait for any pending rx to be received.

Trait Implementations

impl AsyncRead for VmbusSerialDriver

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut [u8], ) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>], ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl AsyncWrite for VmbusSerialDriver

fn poll_write( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize>>
