Enum SignError 

pub enum SignError {
    KeyMismatch {
        expected: [u8; 32],
        got: [u8; 32],
    },
    InvalidSignature,
    Rejected,
    Backend(String),
}

Variants

KeyMismatch

The signer’s public key does not match the message’s expected key.

Fields

expected: [u8; 32]

got: [u8; 32]

InvalidSignature

The signature does not verify over the message (wrong key or garbage; Ed25519 has no key recovery, so the two are indistinguishable here).

Rejected

The signer (or an approver) declined.

Backend(String)

A backend-specific 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, f: &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.
