Crate rufft 

Structs

RealFftPlan

Reusable exact-length F32 FFT plan. The direction and N are fixed; batches may change, in which case the batched workspace is replaced, not grown without bound. Caller-owned output bindings must be non-overlapping. Raw bindings carry no dtype/device tag: pass F32 storage from this client.

Enums

FftMode

Whether doing RFFT or IRFFT.

Functions

exact_convolution_len

Bluestein workspace length. Power-of-two real FFTs use the existing packed real path, which can support up to twice this complex FFT limit.

irfft

Inverse Real-valued Fast Fourier Transform.

irfft_launch

Launches the IRFFT kernel.

irfft_launch_padded

Launches the IRFFT kernel while treating bins at spec_bins..n_freq as zero.

rfft

Real-valued Fast Fourier Transform.

rfft_launch

Launches the RFFT kernel.

rfft_launch_padded

Launches the RFFT kernel while treating samples at signal_len..n_fft as zero.
