Trait SerialIo

pub trait SerialIo:
    AsyncRead
    + AsyncWrite
    + Send
    + InspectMut
    + Unpin {
    // Required methods
    fn is_connected(&self) -> bool;
    fn poll_connect(&mut self, cx: &mut Context<'_>) -> Poll<Result<()>>;
    fn poll_disconnect(&mut self, cx: &mut Context<'_>) -> Poll<Result<()>>;
}

Trait for types providing serial IO.

Required Methods

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.

When the serial backend disconnects, [AsyncRead::poll_read] should return Ok(0).

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

Polls for the serial backend to disconnect.
