Crate baracuda_cufft_sys 

Raw FFI + dynamic loader for NVIDIA cuFFT.

baracuda-cufft wraps this with a safe, typed API. Use this crate directly only if you need a function that the safe layer hasn’t wrapped yet (in which case please file a bug).

cufftDoubleComplex

cuFFT complex (double precision) — layout-compatible with baracuda_types::Complex64.

cufftResult

Return code from a cuFFT call.

Enums

cufftType

cuFFT transform type.

Constants

CUFFT_FORWARD

cuFFT transform direction.
