Enum Error 

#[non_exhaustive]
pub enum Error {
    InvalidLength,
    InvalidModulus,
    InvalidScalar,

    InvalidSignature,

PKA error.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidLength

A value has the wrong length for the curve or modulus it belongs to.

InvalidModulus

The modulus is even, or too large for the operation.

InvalidScalar

A scalar is zero or not smaller than the order of the curve.

InvalidPoint

A point is not on the curve, or is the point at infinity.

InvalidSignature

The signature does not match the message and public key.

NotInvertible

The value has no inverse modulo the modulus.

RetryWithNewK

The nonce produced an unusable signature. Draw a new one and retry.

Hardware

The hardware reported an error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Format for Error

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
