Struct CudaContext 

pub struct CudaContext { /* private fields */ }

CUDA driver context shared by J2K CUDA adapter crates.

Implementations

impl CudaContext

pub fn system_default() -> Result<Self, CudaError>

Create a context for the system default CUDA device.

pub fn retain_primary(device_ordinal: usize) -> Result<Self, CudaError>

Retain the CUDA primary context for a selected device ordinal.

This is the interoperability constructor for runtimes such as CubeCL that also use CUDA primary contexts. Dropping the final clone releases the retain; it never destroys the primary context directly.

impl CudaContext

pub fn synchronize(&self) -> Result<(), CudaError>

Synchronize all work submitted to this CUDA context.

impl CudaContext

pub fn upload_f32_pinned( &self, samples: &[f32], ) -> Result<CudaDeviceBuffer, CudaError>

Upload host f32 samples through a temporary page-locked staging buffer.

impl CudaContext

pub fn upload_pinned(&self, bytes: &[u8]) -> Result<CudaDeviceBuffer, CudaError>

Upload host bytes through a temporary page-locked staging buffer.

impl CudaContext

pub fn upload(&self, bytes: &[u8]) -> Result<CudaDeviceBuffer, CudaError>

Upload host bytes into a CUDA device buffer.

pub fn upload_f32(&self, samples: &[f32]) -> Result<CudaDeviceBuffer, CudaError>

Upload host f32 samples into a CUDA device buffer.

pub fn allocate(&self, len: usize) -> Result<CudaDeviceBuffer, CudaError>

Allocate an uninitialized CUDA device buffer.

pub fn buffer_pool(&self) -> CudaBufferPool

Create a reusable device-buffer pool for this context.

pub fn best_fit_buffer_pool(&self) -> CudaBufferPool

Create a reusable best-fit device-buffer pool for workloads with many same-sized intermediate buffers.

Trait Implementations

impl Clone for CudaContext

fn clone(&self) -> CudaContext

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CudaContext

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

Formats the value using the given formatter.
