Invalid input and unavailable capabilities, independent of signature mismatch.

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.

UnsupportedDomain

A field, basis or domain is outside the implemented capability.

InvalidField

A polynomial fails the required field checks.

InvalidDomain

Curve coefficients, order or base point fail domain validation.

ValidationEvidenceRequired

A custom domain needs independent primitivity/primality evidence.

RandomSampleRefused

The caller’s random source failed to produce a usable bounded sample.

InvalidKey

The public point is malformed, off-curve or outside the subgroup.

InvalidEncoding

The selected encoding has an invalid length or nonzero unused bits.

InvalidDke

A packed substitution table is not eight permutations of 0 through 15.

InvalidOutputSize

The requested hash output length is unsupported.

InputTooLong

An input exceeds the bounded interface or hash-length representation.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

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<E> From<Error> for ValidationError<E>

fn from(value: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
