Struct flate2::CrcWriter

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

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.

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 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.

pub fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

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

pub fn is_write_vectored(&self) -> bool

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

Determines if this Writer has an efficient write_vectored implementation.

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

Attempts to write an entire buffer into this writer.

pub 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.

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

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

pub fn by_ref(&mut self) -> &mut Self

Creates a “by reference” adaptor for this instance of Write.
