Struct Disconnected

pub struct Disconnected;

A SerialIo implementation that is always disconnected.

Trait Implementations

impl AsyncRead for Disconnected

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 Disconnected

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

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close(self: Pin<&mut Self>, _cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to close the object.

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

Attempt to write bytes from bufs into the object using vectored IO operations.

impl Debug for Disconnected

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Disconnected> for Resource<SerialBackendHandle>

fn from(Disconnected: Disconnected) -> Self

Converts to this type from the input type.

impl InspectMut for Disconnected

fn inspect_mut(&mut self, req: Request<'_>)

Inspects the object.

impl SerialIo for Disconnected

fn is_connected(&self) -> bool

Returns true if the backend is already connected.

fn poll_connect(&mut self, _cx: &mut Context<'_>) -> Poll<Result<()>>

Polls for the serial backend to connect.

fn poll_disconnect(&mut self, _cx: &mut Context<'_>) -> Poll<Result<()>>

Polls for the serial backend to disconnect.
