Struct BatchBuffer 

pub struct BatchBuffer { /* private fields */ }

Reusable batch buffer

Implementations

impl BatchBuffer

pub fn new(capacity: usize) -> Self

Create a new buffer with specified capacity

pub fn len(&self) -> usize

Get the current buffer length

pub fn capacity(&self) -> usize

Get current capacity

pub fn is_empty(&self) -> bool

Check if buffer is empty

pub fn as_slice(&self) -> &[u8]

Get buffer contents as slice

pub fn smart_clear(&mut self, shrink_threshold: usize, initial_capacity: usize)

Clear the buffer.

If capacity exceeds shrink_threshold, the internal buffer is dropped and a new one is allocated with initial_capacity. Otherwise, it just clears the vector (keeping capacity).

pub fn clear(&mut self)

Clear the buffer (retains capacity)

Trait Implementations

impl Write for BatchBuffer

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, args: 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.
