Enum NttError 

pub enum NttError {
    InvalidSize(usize),
    NotPrime(u64),
    NotNttFriendly {
        q: u64,
        n: usize,
    },
    PrimeTooLarge(u64),
}

Errors returned by NTT context construction.

Variants

InvalidSize(usize)

N must be a power of 2 >= 2.

NotPrime(u64)

q must be prime.

NotNttFriendly

q must satisfy q ≡ 1 (mod 2N) for NTT.

Fields

q: u64

The modulus that failed the NTT-friendly check.

n: usize

The polynomial size N.

PrimeTooLarge(u64)

q must be < 2^28 for the 32-bit pipeline.

Trait Implementations

impl Clone for NttError

fn clone(&self) -> NttError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NttError

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

Formats the value using the given formatter.

impl Display for NttError

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

Formats the value using the given formatter.

impl Eq for NttError

impl Error for NttError

Available on crate feature std only.

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for NttError

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