Struct tantivy_common::CountingWriter

pub struct CountingWriter<W> { /* private fields */ }

Implementations

impl<W: Write> CountingWriter<W>

pub fn wrap(underlying: W) -> CountingWriter<W>

pub fn written_bytes(&self) -> u64

pub fn finish(self) -> W

Returns the underlying write object. Note that this method does not trigger any flushing.

Trait Implementations

impl<W: TerminatingWrite> TerminatingWrite for CountingWriter<W>

fn terminate_ref(&mut self, token: AntiCallToken) -> Result<()>

You should implement this function to define custom behavior. This function should flush any buffer it may hold.

fn terminate(self) -> Result<()>

where Self: Sized,

Indicate that the writer will no longer be used. Internally call terminate_ref.

impl<W: Write> Write for CountingWriter<W>

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

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

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

Attempts to write an entire buffer into this writer.

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 Writer has an efficient write_vectored implementation.

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.
