Struct tinkv::util::FileWithBufWriter

pub struct FileWithBufWriter { /* fields omitted */ }

A file wrapper wraps File and BufWriterWithOffset<File>. We're using BufWriterWithOffset here for better writting performance. Also, we need to make sure file.sync_all() can be called manually to flush all pending writes to disk.

Implementations

impl FileWithBufWriter

pub fn from(inner: File) -> Result<FileWithBufWriter>

pub fn inner(&self) -> &File

pub fn inner_mut(&mut self) -> &mut File

pub fn sync(&mut self) -> Result<()>

pub fn offset(&self) -> u64

Trait Implementations

impl Debug for FileWithBufWriter

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

Formats the value using the given formatter.

impl Drop for FileWithBufWriter

fn drop(&mut self)

Executes the destructor for this type.

impl Seek for FileWithBufWriter

fn seek(&mut self, pos: SeekFrom) -> Result<u64>

Seek to an offset, in bytes, in a stream.

fn stream_len(&mut self) -> Result<u64, Error>

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

Returns the length of this stream (in bytes).

fn stream_position(&mut self) -> Result<u64, Error>

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

Returns the current seek position from the start of the stream.

impl Write for FileWithBufWriter

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.
