Trait BufferedSerial 

pub trait BufferedSerial: Sync {
    // Required methods
    fn read(&self, buf: &mut [u8]) -> impl Future<Output = usize>;
    fn write(&self, buf: &[u8]) -> impl Future<Output = ()>;
    fn check_dropped_bytes(&self) -> usize;
}

Platform-agnostic buffered serial bridge.

The serial bridge is the inner loop that pumps bytes between the SSH channel and the target UART. Every platform provides a concrete type implementing this trait (ESP32: ssh_stamp_esp32::BufferedUart).

read/write take &self (not &mut self) because the bridge splits each direction into its own future and runs them concurrently via embassy_futures::select::select. Implementations back this with internal pipes / interrupt-filled buffers.

Required Methods

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
