Enum SignError 

pub enum SignError {
    KeyNotFound {
        name: String,
    },
    InvalidKey,
    SignatureFailed {
        context: String,
    },
    WrongCurve {
        expected: String,
        actual: String,
    },
}

Errors that can occur during signing operations.

These errors indicate failures in the cryptographic signing process, including key access and algorithm mismatches.

Variants

KeyNotFound

The requested key does not exist in the key store.

Fields

name: String

The name of the key that was not found.

InvalidKey

The key material is invalid or corrupted.

SignatureFailed

The signing operation failed.

Fields

context: String

Context about why signing failed.

WrongCurve

The key uses a different curve than expected.

Fields

expected: String

The expected curve name (e.g., “secp256k1”).

actual: String

The actual curve name of the key.

Implementations

impl SignError

pub fn key_not_found(name: impl Into<String>) -> Self

Create a KeyNotFound error.

pub fn signature_failed(context: impl Into<String>) -> Self

Create a SignatureFailed error with context.

pub fn wrong_curve( expected: impl Into<String>, actual: impl Into<String>, ) -> Self

Create a WrongCurve error.

Trait Implementations

impl Debug for SignError

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

Formats the value using the given formatter.

impl Display for SignError

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

Formats the value using the given formatter.

impl Error for SignError

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 From<SignError> for SigningError

fn from(source: SignError) -> Self

Converts to this type from the input type.

impl From<SignError> for TxGateError

fn from(source: SignError) -> Self

Converts to this type from the input type.
