Trait Implementations

impl<W: Debug> Debug for CrcWriter<W>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<W: Write> Write for CrcWriter<W>

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

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

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

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

Attempts to write an entire buffer into this write.

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

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