Struct CudaContext 

pub struct CudaContext { /* private fields */ }

CUDA execution context (stub).

Status: Stub. This type exists as an API placeholder when the cuda feature is not enabled. All operations on CudaBackend return errors. Enable the cuda feature for the real implementation.

Examples

// Aspirational API — not yet functional without `cuda` feature.
use tenferro_prims::CudaContext;

Implementations

impl CudaContext

pub fn new() -> Self

Create a stub CUDA context (no-op).

pub fn device_id(&self) -> usize

Return the stub CUDA device ordinal.

Examples

let ctx = tenferro_prims::CudaContext::new();
assert_eq!(ctx.device_id(), 0);

pub fn bind_to_device(&self) -> Result<()>

Bind the stub CUDA context to the current device.

Examples

let ctx = tenferro_prims::CudaContext::new();
assert!(ctx.bind_to_device().is_err());
