Struct BufferedWriter 

pub struct BufferedWriter { /* private fields */ }

A simple in-memory buffered writer.

Accumulates output and allows flushing to a target.

Implementations

impl BufferedWriter

pub fn new(flush_threshold: usize) -> Self

Create a new buffered writer with a given flush threshold.

pub fn default_threshold() -> Self

Create a buffered writer with default threshold (4 KiB).

pub fn write_bytes(&mut self, data: &[u8])

Write bytes to the buffer.

Auto-flushes (clears the buffer) if the threshold is exceeded.

pub fn write_str(&mut self, s: &str)

Write a string to the buffer.

pub fn writeln(&mut self, s: &str)

Write a string followed by a newline.

pub fn flush(&mut self)

Flush the buffer (clear it, simulating a write to an underlying sink).

pub fn as_str(&self) -> Result<&str, IoError>

Get the current buffer contents as a string.

pub fn buffered_len(&self) -> usize

Get the number of buffered (unflushed) bytes.

pub fn total_written(&self) -> usize

Get the total number of bytes written (including flushed).

pub fn is_empty(&self) -> bool

Check if the buffer is empty.
