Implementations

impl<'d> UsbSerialJtag<'d>

pub fn new( usb_serial: impl Peripheral<P = USB_DEVICE> + 'd ) -> UsbSerialJtag<'d>

Trait Implementations

impl ErrorType for UsbSerialJtag<'_>

type Error = Infallible

Error type of all the IO operations on this type.

impl Read for UsbSerialJtag<'_>

fn read( &mut self, buf: &mut [u8] ) -> Result<usize, <UsbSerialJtag<'_> as ErrorType>::Error>

Read some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_exact( &mut self, buf: &mut [u8] ) -> Result<(), ReadExactError<Self::Error>>

Read the exact number of bytes required to fill buf.

impl Write for UsbSerialJtag<'_>

fn write( &mut self, buf: &[u8] ) -> Result<usize, <UsbSerialJtag<'_> as ErrorType>::Error>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<(), <UsbSerialJtag<'_> as ErrorType>::Error>

Flush this output stream, blocking until all intermediately buffered contents reach their destination.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Self::Error>

Write an entire buffer into this writer.

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

Write a formatted string into this writer, returning any error encountered.

impl Write for UsbSerialJtag<'_>

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

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.

impl Read<u8> for UsbSerialJtag<'_>

type Error = Infallible

Read error

fn read(&mut self) -> Result<u8, Error<<UsbSerialJtag<'_> as Read<u8>>::Error>>

Reads a single word from the serial interface

impl Write<u8> for UsbSerialJtag<'_>

type Error = Infallible

Write error

fn write( &mut self, word: u8 ) -> Result<(), Error<<UsbSerialJtag<'_> as Write<u8>>::Error>>

Writes a single word to the serial interface

fn flush( &mut self ) -> Result<(), Error<<UsbSerialJtag<'_> as Write<u8>>::Error>>

Ensures that none of the previously written words are still buffered
