FFT Backend trait for implementing different FFT algorithms

Required Methods

fn name(&self) -> &str

Name of the backend

fn description(&self) -> &str

Description of the backend

fn is_available(&self) -> bool

Check if this backend is available

fn fft(&self, input: &[Complex64], output: &mut [Complex64]) -> FFTResult<()>

Perform forward FFT

fn ifft(&self, input: &[Complex64], output: &mut [Complex64]) -> FFTResult<()>

Perform inverse FFT

fn fft_sized( &self, input: &[Complex64], output: &mut [Complex64], size: usize, ) -> FFTResult<()>

Perform FFT with specific size (may be cached)

fn ifft_sized( &self, input: &[Complex64], output: &mut [Complex64], size: usize, ) -> FFTResult<()>
