#[repr(transparent)]pub struct DifButterflyZeros<F>(pub F);Expand description
DIF (Decimation-In-Frequency) butterfly operation where x_2 is guaranteed to be zero.
Useful in scenarios where the input has just been padded with zeros.
Used in the output-ordering variant of NTT. This butterfly computes:
output_1 = x1
output_2 = x1 * twiddleTuple Fields§
