Serial I/O abstraction for embedded platforms

Required Associated Types

type Error

Platform-specific error type

Required Methods

fn write(&mut self, data: &[u8]) -> Result<usize, Self::Error>

Write bytes to serial port

Arguments

• data - Bytes to write

Returns

Number of bytes written or error

fn read(&mut self, buffer: &mut [u8]) -> Result<usize, Self::Error>

Read bytes from serial port (non-blocking)

Arguments

• buffer - Buffer to read into

Returns

Number of bytes read or error

fn flush(&mut self) -> Result<(), Self::Error>

Flush output buffer

Returns

Ok(()) or error

Provided Methods

fn available(&self) -> Result<bool, Self::Error>

Check if data is available to read

Returns

True if data is available
