Struct DeviceStream 

pub struct DeviceStream { /* private fields */ }

A connected device stream for bidirectional communication.

Implementations

impl DeviceStream

pub fn connect( addr: SocketAddr, bus_id: u32, dev_id: &str, password: Option<&str>, ) -> Result<Self, ViiperError>

pub fn send<T: DeviceInput>(&mut self, input: &T) -> Result<(), ViiperError>

Send a device input to the device.

pub fn on_output<F>(&mut self, callback: F) -> Result<(), ViiperError>

where F: FnMut(&mut dyn BufRead) -> Result<()> + Send + 'static,

Register a callback to receive device output asynchronously. The callback receives a BufRead reader and must read the exact number of bytes expected. The callback will be invoked repeatedly on a background thread until it returns an error. Only one callback can be registered at a time.

pub fn on_disconnect<F>(&mut self, callback: F) -> Result<(), ViiperError>

where F: FnOnce() + Send + 'static,

pub fn send_raw(&mut self, data: &[u8]) -> Result<(), ViiperError>

Send raw bytes to the device.

pub fn read_raw(&mut self, buf: &mut [u8]) -> Result<usize, ViiperError>

Read raw bytes from the device.

pub fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), ViiperError>

Read exact number of bytes from the device.

Trait Implementations

impl Drop for DeviceStream

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
