Struct StreamBuffer 

pub struct StreamBuffer { /* private fields */ }

A reusable buffer for streaming operations.

Manages input and output buffers with efficient memory reuse.

Implementations

impl StreamBuffer

pub fn new() -> Self

Create a new buffer with default size.

pub fn with_capacity(capacity: usize) -> Self

Create a new buffer with specified capacity.

pub fn capacity(&self) -> usize

Get the buffer capacity.

pub fn available(&self) -> usize

Get the number of bytes available to read.

pub fn remaining(&self) -> usize

Get the number of bytes that can be written.

pub fn is_empty(&self) -> bool

Check if buffer is empty.

pub fn is_full(&self) -> bool

Check if buffer is full.

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

Get a slice of readable data.

pub fn writable(&mut self) -> &mut [u8]

Get a mutable slice for writing.

pub fn consume(&mut self, n: usize)

Consume n bytes from the read position.

pub fn advance(&mut self, n: usize)

Advance the write position by n bytes.

pub fn clear(&mut self)

Reset buffer to empty state.

pub fn compact(&mut self)

Compact the buffer by moving unread data to the beginning.

pub fn write(&mut self, data: &[u8]) -> usize

Write data into the buffer.

Returns number of bytes written.

pub fn read(&mut self, buf: &mut [u8]) -> usize

Read data from the buffer.

Returns number of bytes read.

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

Get the underlying buffer for direct access.

pub fn as_mut_slice(&mut self) -> &mut [u8]

Get mutable access to the entire buffer.
