Enum PrfError 

pub enum PrfError {
    ZeroInput,
    InvalidKey,
    InvalidParam,
}

Failure modes for Legendre / Gold PRF operations.

Variants

ZeroInput

(x + K) ≡ 0 (mod p) so the Legendre symbol is zero and the degree-1 PRF is undefined at this point.

InvalidKey

Key material is invalid (e.g. zero or not reduced modulo p).

InvalidParam

Parameter set is malformed (e.g. modulus not odd).

Trait Implementations

impl Clone for PrfError

fn clone(&self) -> PrfError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrfError

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

Formats the value using the given formatter.

impl PartialEq for PrfError

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