Struct FftPlan 

pub struct FftPlan {
    pub key: PlanKey,
    /* private fields */
}

Opaque handle to a cuFFT plan (already materialized through the LRU cache). Callers obtain one via FftActor::ensure_plan or by caching the PlanKey returned from FftPlanMany::key.

Fields

key: PlanKey

Implementations

impl FftPlan

pub fn key(&self) -> PlanKey

pub unsafe fn with_callback( &self, kind: FftCallbackKind, cb: *mut c_void, caller_info: *mut c_void, ) -> Result<(), GpuError>

Install a load/store callback on this plan via cufftXtSetCallback. Returns Err if the runtime libcufft doesn’t expose the Xt API or the call fails.

Safety

cb must be a valid CUDA device function pointer of the signature matching kind. caller_info (if non-null) must outlive every launch on this plan.

pub unsafe fn with_load_callback( &self, kind: FftCallbackKind, cb: *mut c_void, caller_info: *mut c_void, ) -> Result<(), GpuError>

Convenience wrapper: install a load callback.

Safety

See FftPlan::with_callback.

pub unsafe fn with_store_callback( &self, kind: FftCallbackKind, cb: *mut c_void, caller_info: *mut c_void, ) -> Result<(), GpuError>

Convenience wrapper: install a store callback.

Safety

See FftPlan::with_callback.
