Struct UartPanicWriter 

pub struct UartPanicWriter<'a> { /* private fields */ }

A synchronous writer for the QEMU RV32 useful for panics.

For boards that want to use the UART to display panic messages, this provides an implementation of PanicWriter with synchronous output.

This is only to be used by panic messages and is not used within the normal operation of the Tock kernel.

TODO: Validate this UartPanicWriter is always sound to create.

Trait Implementations

impl IoWrite for UartPanicWriter<'_>

fn write(&mut self, buf: &[u8]) -> usize

fn write_ring_buffer(&mut self, buf: &RingBuffer<'_, u8>) -> usize

impl PanicWriter for UartPanicWriter<'_>

type Config = UartPanicWriterConfig

The configuration data the mechanism needs to configure the writer for panic output.

unsafe fn create_panic_writer(config: Self::Config) -> impl IoWrite + Write

Create a new synchronous writer capable of sending panic messages.

impl Write for UartPanicWriter<'_>

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.
