Struct RustFftBackend

Source

pub struct RustFftBackend<T: Scalar + FftNum> { /* private fields */ }

Expand description

FFT backend using the rustfft crate.

This is the default FFT backend for circulant-rs.

Implementations§

Source §

impl<T: Scalar + FftNum> RustFftBackend<T>

Source

pub fn new(size: usize) -> Result<Self>

Create a new RustFFT backend for the given size.

§Errors

Returns InvalidFftSize if size is 0.
