Struct bonsaidb_files::direct::BufferedAppend

pub struct BufferedAppend<'a, Config: FileConfig, Database: Connection + Clone> { /* private fields */ }

A buffered std::io::Write and std::io::Seek implementor for a File.

Implementations

impl<'a, Config: FileConfig, Database: Connection + Clone> BufferedAppend<'a, Config, Database>

pub fn set_buffer_size(&mut self, capacity: usize) -> Result<()>

Sets the size of the buffer. For optimal use, this should be a multiple of Config::BLOCK_SIZE.

If any data is already buffered, it will be flushed before the buffer is resized.

Trait Implementations

impl<'a, Config: FileConfig, Database: Connection + Clone> Drop for BufferedAppend<'a, Config, Database>

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, Config: FileConfig, Database: Connection + Clone> Write for BufferedAppend<'a, Config, Database>

fn write(&mut self, data: &[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 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 Selfwhere Self: Sized,

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