Struct fftw::pair::Pair

pub struct Pair<A, B> {
    pub field: AlignedVec<A>,
    pub coef: AlignedVec<B>,
    // some fields omitted
}

Safe-interface corresponding to out-place transform

FFTW interface modifies an array in fftw_execute function which does not takes the array as its arguments. It is not compatible to the programing model of safe Rust. Pair interface composes the array and plan to manage mutability in the safe Rust way.

Fields

field: AlignedVec<A>

coef: AlignedVec<B>
