Struct Context 

pub struct Context { /* private fields */ }

Struct that holds the context associated with elements in rq.

Implementations

impl Context

pub fn new(moduli: &[u64], degree: usize) -> Result<Self>

Creates a context from a list of moduli and a polynomial degree.

Returns an error if the moduli are not primes less than 62 bits which supports the NTT of size degree.

pub fn new_arc(moduli: &[u64], degree: usize) -> Result<Arc<Self>>

Creates a context in an Arc.

pub fn modulus(&self) -> &BigUint

Returns the modulus as a BigUint.

pub fn moduli(&self) -> &[u64]

Returns a reference to the moduli in this context.

pub fn moduli_operators(&self) -> &[Modulus]

Returns a reference to the moduli as Modulus in this context.

pub fn niterations_to(&self, context: &Arc<Context>) -> Result<usize>

Returns the number of iterations to switch to a children context. Returns an error if the context provided is not a child context.

pub fn context_at_level(&self, i: usize) -> Result<Arc<Self>>

Returns the context after i iterations.

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Context

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

Formats the value using the given formatter.

impl Default for Context

fn default() -> Context

Returns the “default value” for a type.

impl PartialEq for Context

fn eq(&self, other: &Context) -> 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.
