pub enum EcdsaSignatureError {

Why an ECDSA signature cannot be put in its JWS form; see ecdsa_signature_from_der and normalize_ecdsa_signature.

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.

NotEcdsa(JwsAlgorithm)

The algorithm is not ECDSA.

Unsupported(JwsAlgorithm)

The algorithm needs a feature this build does not have: ES256K without secp256k1.

InvalidDer(&'static str)

The input is not a strict DER ECDSA-Sig-Value.

ComponentTooLong

r or s is longer than the curve’s size.

Fields

alg: JwsAlgorithm

The algorithm.

len: usize

The length of the component, without its sign byte.

InvalidLength

A raw signature is not twice the curve’s size.

Fields

alg: JwsAlgorithm

The algorithm.

expected: usize

Twice the curve’s size.

actual: usize

The length of the signature.

OutOfRange(JwsAlgorithm)

r or s is zero or not below the group order.

Trait Implementations

impl Clone for EcdsaSignatureError

fn clone(&self) -> Self

impl Eq for EcdsaSignatureError

impl Error for EcdsaSignatureError

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 EcdsaSignatureError

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

Equality operator ==.

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

Inequality operator !=.
