Struct Crc32cWriter

pub struct Crc32cWriter<W: Write> { /* private fields */ }

Writer wrapper which tracks the checksum of all bytes written.

Implementations

impl<W: Write> Crc32cWriter<W>

pub fn new(w: W) -> Self

Wrap an instance of a Writer.

pub fn new_with_seed(w: W, seed: u32) -> Self

Wrap a Writer, with the checksum seeded with a particular value.

pub fn into_inner(self) -> W

Unwrap the inner Writer.

pub fn crc32c(&self) -> u32

Get the checksum of all bytes written.

Trait Implementations

impl<W: Write> Write for Crc32cWriter<W>

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

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

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

Flushes 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 Writer 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

where Self: Sized,

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