Struct FrameWriter 

pub struct FrameWriter { /* private fields */ }

Writes length-prefixed frames to a byte buffer.

Implementations

impl FrameWriter

pub fn new() -> Self

Creates a new frame writer.

pub fn with_capacity(capacity: usize) -> Self

Creates a new frame writer with the specified initial capacity.

pub fn write_frame(&mut self, payload: &[u8]) -> Result<(), ControlError>

Writes a frame with the given payload.

Errors

Returns an error if the payload exceeds MAX_FRAME_SIZE.

pub fn take_bytes(&mut self) -> Vec<u8>

Takes the accumulated bytes from the buffer.

This clears the internal buffer and returns the data.

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

Returns a reference to the accumulated bytes.

pub fn len(&self) -> usize

Returns the number of bytes currently buffered.

pub fn is_empty(&self) -> bool

Returns true if the buffer is empty.

pub fn clear(&mut self)

Clears the internal buffer.
