baracuda-cufft-sys

Raw FFI bindings + dynamic loader for NVIDIA cuFFT — GPU-side Fast Fourier Transforms.

Symbols resolve lazily via libloading; no link-time dependency on libcufft.so / cufft64_*.dll.

Most users want baracuda-cufft — that crate exposes typed plan builders for 1-D / 2-D / 3-D and many-sized batch FFTs, with all real/complex transform types (R2C, C2R, C2C, D2Z, Z2D, Z2Z), cuFFT-XT multi-GPU plans, and load/store callbacks.

What's exposed

• Plan creation (cufftPlan1d, cufftPlan2d, cufftPlan3d, cufftPlanMany).
• Execution (cufftExecC2C, cufftExecZ2Z, cufftExecR2C, cufftExecC2R, cufftExecD2Z, cufftExecZ2D).
• cuFFT-XT multi-GPU API.
• Set-stream, work-area control, callback registration.
