pub struct CrcWriter<W> { /* fields omitted */ }

[−] Expand description

A wrapper around a Write that calculates the CRC.

Implementations

impl<W> CrcWriter<W>[−]

pub fn crc(&self) -> &Crc[−]

Get the Crc for this CrcWriter.

pub fn into_inner(self) -> W[−]

Get the writer that is wrapped by this CrcWriter.

pub fn get_ref(&self) -> &W[−]

Get the writer that is wrapped by this CrcWriter by reference.

pub fn get_mut(&mut self) -> &mut W[−]

Get a mutable reference to the writer that is wrapped by this CrcWriter.

pub fn reset(&mut self)[−]

Reset the Crc in this CrcWriter.

impl<W: Write> CrcWriter<W>[−]

pub fn new(w: W) -> CrcWriter<W>[−]

Create a new CrcWriter.

impl<W: Write> Write for CrcWriter<W>[+]

[+] Show hidden undocumented items

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

Write a buffer into this writer, 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_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>[−]

Like [write], except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool[−]

🔬 This is a nightly-only experimental API. (can_vector)

Determines if this Writeer has an efficient [write_vectored] implementation.

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

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>[−]

🔬 This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>[−]

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

fn by_ref(&mut self) -> &mut Self[−]

Creates a "by reference" adaptor for this instance of Write.
