Enum SignError 

pub enum SignError {
    AlgorithmUnsupported,
    Provider {
        message: String,
    },
}

Why producing a signature failed.

The shipped local signer is infallible; this exists for remote (broker-backed) implementations whose signing operation can fail.

Variants

AlgorithmUnsupported

The signer does not support the requested algorithm.

Provider

The backing provider (for example an RPC-backed signer) failed. The message is diagnostic transport/provider detail, never key material.

Fields

message: String

Human-readable provider failure detail.

Trait Implementations

impl Clone for SignError

fn clone(&self) -> SignError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for SignError

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 BuildError

fn from(e: SignError) -> Self

Converts to this type from the input type.

impl PartialEq for SignError

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