Struct Broadcaster

pub struct Broadcaster<T> { /* private fields */ }

Broadcast UART recevied data to multiple users.

Normally, if there are multiple users of UART, they share the same buffer (most commonly the kernel buffer). This means that only one user can read a specific piece of data at a time. Broadcaster ensures that all clone of it can receive all data.

Trait Implementations

impl<T> Clone for Broadcaster<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: ConsoleDevice> ConsoleDevice for Broadcaster<T>

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

Reads received data into buf, returning the number of bytes read.

impl<T: Uart> Uart for Broadcaster<T>

fn get_baudrate(&self) -> Result<u32>

Returns the UART baudrate. May return zero for virtual UARTs.

fn set_baudrate(&self, baudrate: u32) -> Result<()>

Sets the UART baudrate. May do nothing for virtual UARTs.

fn get_flow_control(&self) -> Result<FlowControl>

fn set_flow_control(&self, flow_control: bool) -> Result<()>

Enables software flow control for writes.

fn get_device_path(&self) -> Result<String>

Returns "/dev/ttyUSBn" or similar OS device path usable by external programs for directly accessing the serial port.

fn clear_rx_buffer(&self) -> Result<()>

Clears the UART RX buffer.
