Struct InnerPlanner 

pub struct InnerPlanner<T>
where
    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> RealFftPlanner<T>

where T: FftNum,

pub fn new() -> RealFftPlanner<T>

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 forward FFT of the same length, the planner 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 inverse FFT of the same length, the planner will return a new reference to the already existing one.

Trait Implementations

impl<T> Default for RealFftPlanner<T>

where T: FftNum,

fn default() -> RealFftPlanner<T>

Returns the “default value” for a type.
