pub type DispatchFftFn = fn(bool, &DeviceTensor, &DeviceTensor) -> TractResult<()>;Expand description
Per-backend FFT kernel launcher: (inverse, input, output), both interleaved-complex
f32 [lead.., N, 2] (N a supported power of two, transformed axis at rank-2). The
inverse is UNNORMALIZED, matching core Fft (rustfft). The kernel reads N from the
input shape.
