Struct RnsScaler 

pub struct RnsScaler { /* private fields */ }

Scaler for a RNS context. This is a helper struct to perform RNS scaling.

Implementations

impl RnsScaler

pub fn new( from: &Arc<RnsContext>, to: &Arc<RnsContext>, scaling_factor: ScalingFactor, ) -> Self

Create a RNS scaler by numerator / denominator.

Aborts if denominator is equal to 0.

pub fn scale_new(&self, rests: ArrayView1<'_, u64>, size: usize) -> Vec<u64>

Output the RNS representation of the rests scaled by numerator * denominator, and either rounded or floored.

Aborts if the number of rests is different than the number of moduli in debug mode, or if the size is not in [1, …, rests.len()].

pub fn scale( &self, rests: ArrayView1<'_, u64>, out: ArrayViewMut1<'_, u64>, starting_index: usize, )

Compute the RNS representation of the rests scaled by numerator * denominator, and either rounded or floored, and store the result in out.

Aborts if the number of rests is different than the number of moduli in debug mode, or if the size of out is not in [1, …, rests.len()].

Trait Implementations

impl Clone for RnsScaler

fn clone(&self) -> RnsScaler

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RnsScaler

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RnsScaler

fn default() -> RnsScaler

Returns the “default value” for a type.

impl PartialEq for RnsScaler

fn eq(&self, other: &RnsScaler) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
