Struct CudaBurnDecoder 

pub struct CudaBurnDecoder { /* private fields */ }

Persistent CUDA codec session followed by an explicit staged Burn upload.

JPEG 2000 decoding executes on CUDA. Completed codec-owned device output is copied to host staging and then uploaded through burn_core::tensor::Tensor::from_data. This type does not provide direct-destination or zero-copy behavior.

Implementations

impl CudaBurnDecoder

pub fn new(device: CudaDevice, options: BatchDecodeOptions) -> Self

Create a staged decoder for one Burn CUDA device.

pub const fn codec(&self) -> &CodecDecoder

Borrow the persistent CUDA codec session.

pub const fn device(&self) -> &CudaDevice

Borrow the Burn CUDA device receiving the staged upload.

pub fn prepare( &self, inputs: Vec<EncodedImage>, ) -> Result<PreparedBatch, BurnDecodeError>

Parse and group owned inputs once for repeated decode calls.

pub fn prepare_prepared_images( &self, images: Vec<PreparedImage>, ) -> Result<PreparedBatch, BurnDecodeError>

Regroup caller-supplied prepared images without reparsing codestream bytes.

pub fn decode( &mut self, inputs: Vec<EncodedImage>, ) -> Result<BurnBatchDecode<Cuda>, BurnDecodeError>

Decode on CUDA, stage completed pixels through host memory, and upload to Burn.

pub fn decode_prepared_images( &mut self, images: Vec<PreparedImage>, ) -> Result<BurnBatchDecode<Cuda>, BurnDecodeError>

Regroup prepared images, decode on CUDA, and perform the staged upload.

pub fn decode_prepared( &mut self, prepared: &PreparedBatch, ) -> Result<BurnBatchDecode<Cuda>, BurnDecodeError>

Decode a reusable preparation on CUDA and perform the staged upload.

pub fn submit( &mut self, inputs: Vec<EncodedImage>, ) -> Result<SubmittedCudaBurnBatch, BurnDecodeError>

Submit CUDA codec work. The later SubmittedCudaBurnBatch::wait performs a synchronous device-to-host copy and ordinary Burn upload.

pub fn submit_prepared( &mut self, prepared: &PreparedBatch, ) -> Result<SubmittedCudaBurnBatch, BurnDecodeError>

Submit a reusable preparation to codec-owned CUDA output.

Trait Implementations

impl Debug for CudaBurnDecoder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
