Enum CurveError 

pub enum CurveError {
    NotPrime,
    Singular,
    NotComplete,
    NotOnCurve,
    WrongOrder,
}

Why a curve can’t be built from its parameters.

Variants

NotPrime

The modulus is not a prime above 3.

Singular

The curve has a singular point: its discriminant is zero modulo the prime.

NotComplete

The twisted Edwards addition law is not complete: a must be a square and d not.

NotOnCurve

The generator of a Domain is not on its curve.

WrongOrder

The order given for a Domain is not a multiple of its generator’s.

impl Eq for CurveError

impl Error for CurveError

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 CurveError

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

Equality operator ==.

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

Inequality operator !=.
