Implementations

impl Plan32

pub fn try_new(n: usize) -> Option<Self>

Returns a negacyclic NTT plan for the given polynomial size, or None if no suitable roots of unity can be found for the wanted parameters.

pub fn ntt_size(&self) -> usize

Returns the polynomial size of the negacyclic NTT plan.

pub fn fwd( &self, value: &[u128], mod_p0: &mut [u32], mod_p1: &mut [u32], mod_p2: &mut [u32], mod_p3: &mut [u32], mod_p4: &mut [u32], )

pub fn fwd_binary( &self, value: &[u128], mod_p0: &mut [u32], mod_p1: &mut [u32], mod_p2: &mut [u32], mod_p3: &mut [u32], mod_p4: &mut [u32], )

pub fn inv( &self, value: &mut [u128], mod_p0: &mut [u32], mod_p1: &mut [u32], mod_p2: &mut [u32], mod_p3: &mut [u32], mod_p4: &mut [u32], )

pub fn negacyclic_polymul(&self, prod: &mut [u128], lhs: &[u128], rhs: &[u128])

Computes the negacyclic polynomial product of lhs and rhs, and stores the result in prod.
