Struct realfft::RealFftPlanner

pub struct RealFftPlanner<T: FftNum> { /* private fields */ }

A planner is used to create FFTs. It caches results internally, so when making more than one FFT it is advisable to reuse the same planner.

Implementations

impl<T: FftNum> RealFftPlanner<T>

pub fn new() -> Self

Create a new planner.

pub fn plan_fft_forward(&mut self, len: usize) -> Arc<dyn RealToComplex<T>>

Plan a Real-to-Complex forward FFT. Returns the FFT in a shared reference. If requesting a second FFT of the same length, this will return a new reference to the already existing one.

pub fn plan_fft_inverse(&mut self, len: usize) -> Arc<dyn ComplexToReal<T>>

Plan a Complex-to-Real inverse FFT. Returns the FFT in a shared reference. If requesting a second FFT of the same length, this will return a new reference to the already existing one.

Trait Implementations

impl<T: FftNum> Default for RealFftPlanner<T>

fn default() -> Self

Returns the “default value” for a type.
