Struct BufferedUart 

pub struct BufferedUart { /* private fields */ }

Bidirectional pipe buffer for UART communications.

Implementations

impl BufferedUart

pub fn new() -> Self

pub async fn run(&self, uart: Uart<'_, Async>)

Transfer data between UART hardware and internal buffers.

This should be awaited from an Embassy task run in an InterruptExecutor for lower latency.

pub async fn read(&self, buf: &mut [u8]) -> usize

pub async fn write(&self, buf: &[u8])

pub fn check_dropped_bytes(&self) -> usize

Number of bytes the RX side dropped since the last call. Resets the counter.

Trait Implementations

impl BufferedSerial for BufferedUart

fn read(&self, buf: &mut [u8]) -> impl Future<Output = usize>

Read as many bytes as are available, up to buf.len(). Returns the number of bytes read. Awaits until at least one byte is available.

fn write(&self, buf: &[u8]) -> impl Future<Output = ()>

Queue bytes to be written. Completes once buf has been accepted by the internal buffer (may still be in flight on the wire).

fn check_dropped_bytes(&self) -> usize

Return how many received bytes were dropped since the last call due to the internal buffer being full. Resets the counter.

impl Default for BufferedUart

fn default() -> Self

Returns the “default value” for a type.
