Struct BytesEncoder 

pub struct BytesEncoder { /* private fields */ }

Encoder for raw byte input with explicit pixel layout.

This encoder wraps StreamingEncoder to provide true streaming encoding without buffering the entire image in memory.

Implementations

impl BytesEncoder

pub fn push( &mut self, data: &[u8], rows: usize, stride_bytes: usize, stop: impl Stop, ) -> Result<()>

Push rows with explicit stride.

• data: Raw pixel bytes
• rows: Number of scanlines to push
• stride_bytes: Bytes per row in buffer (>= width * bytes_per_pixel)
• stop: Cancellation token (use enough::Unstoppable if not needed)

pub fn push_packed(&mut self, data: &[u8], stop: impl Stop) -> Result<()>

Push contiguous (packed) data.

Stride is assumed to be width * bytes_per_pixel. Rows inferred from data.len() / (width * bytes_per_pixel).

pub fn width(&self) -> u32

Get image width.

pub fn height(&self) -> u32

Get image height.

pub fn rows_pushed(&self) -> u32

Get number of rows pushed so far.

pub fn rows_remaining(&self) -> u32

Get number of rows remaining.

pub fn layout(&self) -> PixelLayout

Get the pixel layout.

pub fn finish(self) -> Result<Vec<u8>>

Finish encoding, return JPEG bytes.

pub fn finish_to<W: Write>(self, output: W) -> Result<W>

Finish encoding to Write destination.

pub fn finish_to_vec(self, output: &mut Vec<u8>) -> Result<()>

Finish encoding, appending JPEG bytes to an existing Vec.

Useful for no_std environments or buffer reuse.
